    This post is essentially an update to one made earlier this month. Demand for astronomy equipment during the pandemic is very high. Higher even than Christmas! But whilst China have reopened, manufacturers are struggling with high demand, materials shortages and reduced shipping channels. A perfect storm! In an attempt to stay on top of the situation 'everyone' at FLO is working overtime. My own working day starts at 5am, seven days a week, and has done for a while. We have also employed two extra full-time people in dispatch (Nathan & Dan) and another full-time person (Alex) for the Helpdesk. Our biggest challenge is how to keep our websites stock availability indicators up-to-date and our customers informed during such a turbulent time. Doing this for Sky-Watcher products is especially difficult. We source most products direct from the manufacturer and hold stock at our warehouse but in Europe retailers must source Sky-Watcher products through a distributor. All communications to/from Synta (Sky-Watcher) are through a distributor. The distributor closed when the lockdown began then reopened with reduced staff. They are working hard in difficult circumstances to catch up but are only now finding how many products sold while they were closed and how little is coming out of China. It has not been possible for them to keep us regularly updated. Normally we practice a duck-on-water approach (calm on the surface while paddling like crazy underneath!) but we are past that. We are predicting it will take China 3-4 months to catch up so I think it important we share this with you (this situation affects all astronomy retailers) and ask you to please continue being patient until supply has caught up with demand. On a positive note. Interest in astronomy is at an all-time high and FLO has never been in such good health with a warehouse full to bursting and more staff than you can shake a stick at. Thank-you sincerely for your patience and understanding during these extraordinary times. Alex, Annette, Ann, Dan, Grant, Ian, James, Katie, Lisa, Martin, Nathan, Rob & Steve

    While the clouds have scuppered me for the past week i thought i would revisit some older data. Taken a couple of weeks ago with the C925, 178mm and 642 ir pass filter, best 15% of 2.5k frames. Probably the clearest image i have ever taken of an Apollo landing site. For reference.

    There have been lots of really excellent M101's posted on SGL of late but for the record here is my attempt. This is the final data set of my spring galaxy imaging (although actually I captured the data for this before any of the others on a couple of clear nights in late March and I will be posting a reprocess of the Whale Galaxy at some point). This was first light for my new Esprit 150 and sadly I didn't nail the guiding (the scope is at the limit of what my CEM60-EC can handle) which has impacted on the blue channel in particular. I took 60, 180s subs in each channel and stacked the best 40 of each for a total integration time of 6hrs. 3 minute subs are just enough, I think. Only the very centre of HIP68503 (TYC3852-468-1) and a couple of the other bright stars were saturated and the signal in the galaxy was OK but I think 300 second subs would have produced a better result on the outer spiral arms so I think that I will use 5 minute subs for this sort of target with this set-up in the future. Kit was CEM60-EC; SW Esprit 150; Atik EFW2 with Astrodon filters; Atik OAG with a mono QHY5L II; Atik 460ex. Data acquired using SGPro, guided with PHD2 and processed in PI and PS. This version is the straight RGB, processed as best as I can: This is a version with all 120 of the R,G, and B subs stacked together to create a synthetic luminance. Whilst I didn't go crazy sharpening the resulting luminance layer, I think it does add a bit of detail and contrast. As an aside, in the second StarGaZine instalment, Nik Szymanek (for whom I have the greatest respect) was not convinced that a synthetic luminance adds anything, if I understood correctly because you obviously don't actually have any more data. However you are, of course, utilising that data in a different way. Stacking all of the subs using an algorithm like sigma clipping gives a different result to layering the 3 individual stacks (not least because you have 3 times the number of subs for the low-signal sky background which I'd argue is more or less the same through each filter unless you have bad light pollution). All that said, as I have been discussing with @MartinB, I think in future I will return to putting most of my effort in to getting a good luminance data set and bin the colour as I have done with previous images of M51 and M81. Finally here's the annotated version from PI. Apols for the long post! Clear skies, Ian

    Another great morning capturing this beauty of a comet. I really hope she holds together as she passes around the sun. I think even more people will get a chance to view it once it's in the early evening sky. But I'm not complaining about getting up at 1am, leaving the house at 1:30am, arriving at my observing location at 2:15am and heading home at 5:15am. It was worth every minute. And my dogs were happy to get a run in the park at 5:30am before the triple-digit temps hit us yet again here in the Vegas Valley. I'm still working on a wide-angle timelapse of the comet rising in the east that I'll share later in a separate post but here's three closeup's from today. If you remember my post from yesterday, I was using my ED127mm which is 655mm focal length with the reducer/flattener. Well, today I took my StellarVue SV70T which is 380mm with the reducer/flattener because I wanted to try and capture all of the tail. It's TOO BIG even for the 380mm to really capture the whole thing! Comet C/2020 F3 Neowise StellarVue SV70T with .8x reducer flattener (380mm FL) ZWO ASI1600mm cooled camera (-15°) This is a series of multiple exposures at 30 seconds, 15 seconds, and 10 seconds through LRGB filters totaling 25 minutes, 40 seconds. You can make out the pale blue ion tail trailing off the left side in this image. 15-second exposures through LRGB totaling 300 seconds 10-second exposures through LRGB totaling 200 seconds. In this frame, you can really see dawn fast approaching.

    It had been a long time since I'd processed narrowband data so I was very encouraged by the response to the image of Melotte 15 that I posted a couple of weeks ago - thank you for all the comments and likes which were much appreciated. I was really happy with that image when I posted it but as I've lived with it I began to dislike that the central column of gas (that some call the dancing man - but I can also see what looks like a peacock in there!) was so yellow and it also began to look a bit blocky and unrefined. Thanks to some great advice from @ollypenrice and @Martin-Devon I've done a couple of reprocesses and each time, I think, improved the result. Now I still think @swag72's version sets the bar, and my rendition comes nowhere near matching hers but I've been over this data so many times that I am calling this finished. I have, though, learnt so much processing this data (which is the same as before: 10 hours of Ha in 600s subs and a further 18 hours of OIII in 1200s subs) and it makes me want to go back and reprocess a lot of the other narrowband targets that I've never really been happy with! Anyway, here is the reprocessed version: Same kit, obviously, but for completeness: TS Optics 130 Apo; iOptron CEM40; Atik OAG with QHY5L II; Atik EFW2 with 5nm Ha and 3nm OIII Astrodon filters; Atik 460 ex. Captured using SGPro and processed using PixInsight and PS. Thanks for looking, Ian

    Set my alarm for 1.30 this morning, drove out into the mendips and dragged by backside and gear up to the highest point, Black Down Hill for panoramic views over Bristol. The beautiful comet and NLC display made it very worth it! Comet was easily naked eye and filled the FoV of my 8x50 bins. Pics with 1200d and Sigma 18-200mm.

    This is taken over 4 nights, but some nights I didn't collect much due to cloud, short nights and Clamshell dome obstruction Now fixed) I decided not to waste any more time trying to reveal the Squid in Bortle 8, though I did do twice as much data on Oiii as the Ha with a fast lens. In total: Ha 12 x 600secs (total 2 hours) Oiii 2 x 20mins, 2 x 30mins, and 7 x 15mins 3 x 900secs binned x 2 (total 4 hours 10 mins) Atik460EX and Samyang 135mm F2 lens @ F2.8 Guided on HEQ5 Total imaging time 6 hours and 10 mins.

    This has been my June project. 4 x 20 minutes subs from the Tak Epsilon with an Ha filter. I didnt really plan on a mosaic but I was just manually aligning it whilst I was trying to get everything setup in a new obsy (and and a new profile - in SGP there seems to be two places that you have to enter the same data). I used SGP autofocus and was pleased that it seems to be working well. I need an earlier night to sit out and do proper configuration of the pier etc. I didnt do much processing of it, just stacked in APP, and processed lightly in PS. Thanks! Adam.

    Several beautifully rendered bicolor images of this target prompted me to make the attempt. Conditions started out fairly poorly for the Ha, but improved greattly for the OIII. Wolf Rayet stars spawn some of the most interesting targets in the heavens in my opinion, from Thor's Helmet to the Cresecnt Nebula, to this intriguing example. I knew it was going to be tough to pick up the full bubble, so I am fairly pleased in that much of the blue circular area is visible--though faintly. Bicolor images always give me trouble. This one was no exception. I was surprised at the amount of OIII emission not associated with the main feature--the arc structure and fainter bubble. I am just guessing, but it seems WR-134 must be a monstrously powerful star and the OIII throughout this image, having originated from the star, has been blwon out into the surrounding region. Then again--maybe it s just me!....regulating background OIII is one of the cjallenges for me with HOO images TOA 130 with .7x reducer and ASI 1600mmcool pro with 3nm Astrodon filters Ha: 137 300 sec OIII: 133: 300 sec Reduced stras a bit--not sure which I like better

    A dreamy look of a fascinating galaxy. Short integration time and under far from ideal conditions due to full moon when Luminance was taken. Many hours went to achieve good natural colour unlike my mad M101 taken earlier. More details here; https://www.astrobin.com/tqkjvu/

    Not quite happy with the background, will add flats and darks later, but very happy with the level of detail in this stack of 9 images taken with my Canon EOS 80D with Sigma 50-100mm F/1.8 ART zoom at 100mm on my EQ3-2 mount, each exposure 30 s at F/1.8, ISO 200. The tail is clearly longer than the FOV of my 200mm F/2.8. I am also very pleased at the performance of this Sigma zoom at full aperture. Clearly not just a perfect portrait zoom, but excellent at wide-field astro-imaging

    This is my first naked eye comet and second comet ever(Wirtanen being my first) and I was truly amazed with how it looked through my Helios Apollo 15X70 binoculars! The tail was so obvious and just barely visible with averted vision naked eye. I really hope I get one more change to see this comet, but the weather here in Denmark isn't great at the moment... Just to share the images here as well, here they are: This single widefield shot is cropped almost 100% and shot with a 50mm prime lens at about 03:30AM Stack of 32X1sec exposures with 100ISO through the Evostar 72. These were shot right before the previous widefield image. I really hope everyone will have the opportunity to see this comet! It was truly amazing to see as my first ever naked eye comet. Compared to Wirtanen, which was a small fuzzy star through my Helios Apollo 15X70, this comet is a lot more exciting and the tail is beautiful! Clear skies, Victor

    Hi all, I have a DSLR only setup (with a SA Mini Wifi tracker) and have only been in this wonderful game a couple of months., so I have lots to learn still. This was my attempt at M27 last night from B6 skies. I was quite surprised that I managed to get 3.5 mins exposures with my mount as many people have said 1 min maximum would be achievable. Considering my incredibly cheap and basic setup...i'm pretty pleased with the result. What say you all? Go for the jugular, I can take it.

    Friday was an exciting day as my 10mm Delos arrived. I have a 9mm Lunt XWA which is a great 100 degree eyepiece but lacks in sharpness and contrast compared to my favourite 9mm ortho (BGO). I've been pondering for quite awhile whether to sacrifice some FOV to get better contrast and sharpness. The 10mm Delos is my experiment to see how that works out in practise. It was after midnight before I got out with the 10" dob. I spent some with Jupiter and Saturn to start with. Initially, I struggled with the eye relief on the Delos but then I discovered the twist up mechanism and all was well. On Saturn, the first thing that grabbed me was that I could easily pick out Rhea and Dione with the Delos. A good sign. After that I moved onto some DSO's, M71 and then M27. I added the Lumicon UHC filter to M27. The mag 11 star on the corner of the dumbbell seemed to really pop in the Delos when compared to the Lunt. Comet C/2017 T2 and a collection of galaxies in Ursa Major all showed well. M51 showing the slightest hint of spiral arms in the TV eyepiece. A tantalising hint of what this eyepiece may show under dark skies. I finished up my eyepiece testing on M13 and it's companion galaxy NGC 6207. The propellor in M13 put in an appearance which was great to see. Looking overhead the Milky Way was very clear for my suburban skies. I wandered inside to grab the camera and took some photos. Taking the camera with me, I strolled out into the street to see if I could find a place to shoot the Milky Way with Jupiter and Saturn. I then spotted some lovely Noctilucent clouds on the horizon so starting walking a little further to try and get a good shot of them. Ended up walking over a mile, meeting a hedgehog who I assume was just getting back from the pub. As I returned back to my house, I spotted that Mars was well risen. With the time now around 2:30am, I spent 10 minutes or so with the red planet. I was able to see some nice dark features on the surface and a light area on the bottom of the planet which I took to be a polar ice cap. Great way to finish the night. Finally crawled into bed at 3am. Pictures below. I'm still a beginner, especially with processing images but I'm improving.

    This is undoubtedly one of my favourite emission nebulae targets - the gas and dust around the Melotte 15 star cluster at the heart of the Heart Nebula. Melotte 15 comprises of mostly young, hot, blue stars which are 'only' around 1.5 million years old. Some of these are around 50 solar masses but most are smaller than our sun. I collected 10 hours of Ha in 600s subs and a further 18 hours of OIII in 1200s subs. I think this is the most data I've ever captured on a target and the first time I've gone over 100,000 seconds; it made the data a dream to process. The Ha signal is very strong and OIII covers most of the frame so I spent most of my time playing with endless variations of the balance between golds and purples - and I could have posted a dozen variants! As it is I've taken my time and settled on this as my favourite rendition. The data meant even the lowest signal areas were pretty clean and after much procrastination this version does have some noise reduction applied. I'd be really interested in views on whether it's too much and I should have left it alone - I really hope that I've done the data and the target justice. I first imaged this back in 2013 but vowed to go back with a longer focal length so this is with my 130mm TS apo (860mm focal length, f/6.6). I've gone for a similar palette to my earlier version because I like the colours so much. I did capture about 5 1/2 hours of RGB data but I haven't used it in this image as it didn't really add anything (most of the stars a blue anyway) but I will come back to the data and do a version where I add some of the narrowband data to the RGB. Kit used was TS Optics 130 Apo; iOptron CEM40; Atik OAG with QHY5L II; Atik EFW2 with 5nm Ha and 3nm OIII Astrodon filters; Atik 460 ex. Captured using SGPro and processed using PixInsight and PS. Thanks for looking, Ian

    Manage to capture comet C/2020 F3 (NEOWISE) in the early hours. First needed to dodge some clouds, but later they moved off, allowing me to capture a series of 37 shots with the 200 mm F/2.8, which I stacked in AS!3 and cropped and stretched in GIMP. Quite pleased with this first naked eye comet in 24 years. and with comet number 29 in total.

    Hi What a great time to be enjoying astronomy. So many fantastic photos on the forum and the internet in general. Here is one from 2am this morning from a local beauty spot just up the road from me. "Beaghmore is a complex of early Bronze Age megalithic features, stone circles and cairns, on the south-east edge of the Sperrin Mountains. Possibly the site could mark a focal point for religious and/or social gatherings. Some archaeologists believe that the circles have been constructed in relation to the rising of the sun at the solstice, or to record the movements of the sun and moon acting as observatories for particular lunar, solar or stellar events. Three of the stone rows point to the sunrise at the time of the solstice and another is aligned towards moonrise at the same period. However, most of the remains at Beaghmore do not indicate very accurate alignments upon specific astronomical features." I used my Nikon D800E and an old Tokina 28-70mm F2.6 lens, 30s exposure on a SA mount. Thanks for looking Adam

    Achieved first light with the new SW Heritage 150p last night. I set it up on the patio table. It’s very quick and easy to set up. The scope + mount is stored in a cupboard, so I simply lifted it out and used the built in carry handle cut-out to take the whole thing outside and plonk it down on the table. Easy. Extending the collapsible tube is quick too. I checked the collimation with a laser collimator and it was almost spot on – as it was the other day when first delivered. First thing was to align the red dot finder on Arcturus. I must say I do not like these small red dot finders and this one seem particularly poor. The adjustment screws are pretty hard to move (without jogging the main scope) and don’t seem to work very well. Moreover, the orange tinted front glass reduces transparency and scatters light. I’ve got a few more of these dreadful 1x power red dot finders and one without the tinted glass (if it is glass, that is!!), so I might swap. I then inserted a Panoptic 24 mm eyepiece(x31) and focused on Arcturus. The focuser isn’t brilliant, but I wasn’t expecting it to be perfect. It works pretty well, though, and achieving focus was easy. Note that I had wound some PTFE tape around the focuser thread which reduces play and makes focusing smoother. There is some play in the focuser unit as it’s made of plastic. But, again, it’s acceptable given the intended purpose of the instrument – and its price point. Arcturus and surrounding stars were pint point. Lovely view, actually. Of course the 6 diffraction spike were visible (due to the 3 vane spider). A bit of a novelty for me as a refactor user normally! Turning to M13, again a lovely wide-field view with the Pan 24 (just over 2 degrees x31). I inserted a Nagler 9mm (x83) and the outer edges were resolved. It occurred to me that the Nagler eyepiece cost 50% more than the Heritage 150p which shows what good value the scope is (or, perhaps, how expensive Naglers are ) Next was M57, the Ring Nebula. Again easily found and benefiting from the Nagler 9mm. Finally, I scanned part of the Summer Milky Way in Cygnus. I think this is where the ‘scope will be used a lot at dark sites as the Pan 24 gives a stunning wide-field vista as one moves through all those amazing star fields. The dob mount performed well and was smooth enough in both alt and az, especially when I’d adjusted the friction tension. So, all in all I think this is an excellent telescope. The optics are excellent and the views wonderful. It’s also highly desirable to have 6 full inches of aperture to hand! Yet it’s compact and light enough to put in a small car for a holiday under dark skies. The folding tube assembly obviously has some limitations and the weak points are the focuser (although this can be improved with the PTFE tape) and the red dot finder. I also have a SW 150 f/8 Dobsonian. This is the solid tube version. I gave it to my younger daughter for her 9th birthday and she’s now a junior doctor, so I’ve had it a while . Mechanically this is much better and the solid tube a real benefit. But it is bulky and not really suitable to take away by car, unless it was the only thing I had on board. If I had to chose between the two, I’d go for the solid tube longer FL ‘scope if I was only intended to use at home. I also tried the Heritage 150P OTA on two other mounts. The SW AZ5 on a Berlebach Report 312 gives much smoother alt az motions that the Heritage dob base. I also tried the OTA on a SW AZ-GTi: a super combo and this will be great for dark nights away. The goto will allow loads of objects to be swept up easily. I think I will prefer using one of these mounts on occasion, but of course it partly negates the compact dob package that the Heritage offers. You can’t beat the simplicity of grabbing the heritage, setting it on a table and be observing in a couple of minutes!

    Hi Guys I thought I'd post this as I've not posted on this section before because I'm mainly a planetary imager. There is around 5 hours 45 mins of data here, taken with a QHY8L OSC camera and the C14 with a reducer. Focal length was 2.7 metres. Comments and constructive criticism always welcomed, but I hope you enjoy it. All the best Harvey NGC 4565.tiff

    I've been in SW Ireland since March, and my neighbour has been looking after where I live SW of London. As a gesture of thanks for his efforts, a couple of weeks ago I sent him unannounced a Heritage 150p, as he has expressed an interest in my astro shenanigans in the past. Last Monday I had to go back to London for a week or so after an unexpected terribly sad family event. But I did get to have a strange night's observing, followed by an afternoon. Wednesday I think I was out on my patio near midnight with my LZOS 105mm refractor on Skytee2, cruising through Ursa Major as I recall, and I could hear he was using his scope the other side of the 8 foot brick wall between our patios. then I heard him whisper-shout a faint "Magnus?". What ensued was me guiding him around the sky, shouting as quietly as we could over the wall. I think I started him out on too difficult a very first ever target, Epsilon Lyrae. His 12-year-old daughter (it was really her present) was operating the iphone and instructing him as to what he should be seeing. They hadn't been able to line up their RDF properly, so their navigation was a little difficult. But they eventually did find the Double-Double, but couldn't quite split the pairs. They were just aware that one of the doubles was not a point. To be fair, even with my 4" using similar maginfication I couldn't quite split one of them either. I then directed them to Mizar/Alcor. They were using a SW LET 25mm eyepiece (30x) and again trying to find it without a finder or RDF. Nonetheless they found it quite quickly, and I found it so gratifying when I heard over the wall "Ah, found it. Oh. Oh. Oh my goodness, Oh God that's lovely! Sophia [his 12-year-old], come and look at this!". I arranged for the next afternoon to go round and see how well it was collimated "out of the box" (not very well, as it turned out), and to see if we could find "daytime Venus". Around 1pm, I went round, collimated it, it was quite a bit out, and hunted around for Venus, 29 degrees or so away from the Sun. Having resaerached where it should be using the app "Sky Guide" (which I really like) he found Venus quite quickly through 10x50 bins, and eventually I found it in the scope. He was amazed a planet was so visible when you found it yet so not-noticeable, in total broad full-sunshine (30 degrees C !!!!!). I swapped in my DeLite 18.2 instead of his SW 25mm LET, and there really wasn't that much difference! I'd given him also my 9mm and 25mmm LETs that came new with my mak180. Those LETs are a very good improvement over the regular OEM SW eyepieces. So, all in all, I recruited one, very likely two, to this game of ours, and had a very memorable evening and afternoon. To offset the otherwise sad reason for my week's return to London. M

    Not a lot of astrophoto going on this time of year but 2 days ago I got a magnificent display of NLC down by the lake close to where I live. I also managed to capture Neowise but it´s too small to be visible here This was only stitched in Lightroom so there are a few artifacts. Need to do it in a proper panorama program. Someday...

    I've wanted a permanent setup for a while now but my wife for some reason did not take kindly to the suggestion of a Todmorden pier in the middle of the lawn. We eventually agreed that a permanent pier could be tucked away in the northwest corner of the garden provided it could be covered up and hidden. However, I set up my kit there several times last year and discovered that The problem with that corner of the garden is that in the southeast corner of the garden is our patio and summerhouse and tying to observe from there was like viewing targets through a stream due to the heat given off by the patio slabs and summerhouse roof. At the end of last year, I managed to pick up a Skywatcher Pillar Mount from @Stu. The pillar mount wasn't initially received well by Mrs K and I was resigned to the fact that the mount would live in pieces in the garage until I could be bothered to sell it. However, fast forward three months to the beginning of Covid Lockdown and I decide to brave the wrath of Mrs K and set up the Pillar Mount in the garden and set about using it virtually every day. The mount was set up on a set of vibration suppression pads, mainly to stop the height adjustment bolts from sinking into the lawn. I personally didn't think much of the anti-vibration pads as they seemed to add more vibration than they got rid of to be honest. Eventually having seen how much more use I've had out of my equipment Mrs K agrees that I can have a semi-permanent setup in the garden provided it is easily moved so it can be hidden when we have visitors and doesn't involve pouring a huge block of concrete or paving a large area in the middle of the lawn...........and under no circumstances were hollow concrete blocks to be involved. I'm a visual only observer and so didn't need to sink a tonne of concrete in the garden, and I originally suggested setting out three paving slabs, one for each foot of the Pillar, but this met with disapproval, as did the solution that involved filling short lengths of plastic 4" waste pipe in the ground. Anyway, I had another think and eventually came up with the idea of filling some terracotta plant pots with concrete, enlarging the drain holes in the bottom of the pots to 16mm diameter to take the levelling adjustment bolts of the pillar and then sinking the pots into the lawn. I figured that the terracotta pots blended in quite well with the garden and would green over with moss fairly quickly and the 16mm holes in the pots would allow me to re-locate the mount pretty accurately after moving it to mow the lawn. This plan got the seal of approval, and deciding that it would be prudent to act quickly before decisions were reversed I sprang into action and spent the weekend sorting things out. 1) - Turf Cut 2) - Holes Dug 3) - Type 1 aggregate tamped down and concrete placed to hold pots. 4) - Holes backfilled, holes cut in turf and turves replaced 5) - Mount put in position I got first light with the setup last night and am pleased to report that the stability of the setup is very much improved over the original setup with the anti-vibration pads.

    Just looking at what I have so far on IC 1318....a total of only 6 hours 20 minutes. I'll be aiming for 20 hours or more....if I don't need to spend weeks looking for that much. It will interesting to see if the extra time will be worth the trouble....but I'll try for it anyway.

    I m happy to say that the 400hr Orion image is now available to view at 40% full size through Zoomify on my website. Click on the Full Screen button then zoom and pan away. https://www.astrophotography.ie/mosaics.htm This is almost the 1.8m x 1.0m size that I print out as the largest size. So now you can see the Mosaic as it was meant to be seen. Big, very big. The 14hrs per frame really shows in the detail, colour and quality as you zoom in and in. The overlays of the 1m data from the TECs on M42, Horsehead, Running Man, and M78 look excellent at this size too. I hope you enyoy it in a new way. Thanks to my friend John Caffrey for working on the site, and to Olly Penrice for joining me in this project. Tom.

    Hey guys/gals, here's the video of the comet that I created from a series of my stills. Details: Canon 5D MarkII, 24-70mm f2.8 lens, ISO 400, Shutter speed starts out at 15 seconds but changes to 2 seconds and finally 1/2 second as dawn arrives. You'll see the jump in exposures. The closeups at the end you have probably already seen here in an earlier post. I'd love to get some new subscribers to my new YouTube channel. Will you be the person that puts me in double-digits?! https://youtu.be/J-W-7Ioohr8

    Regular Clouds, Noctilucent Clouds, a Cityscape and a Comet. Unfortunately by the time the Noctilucent Clouds came along Comet C/2020 F3 (NEOWISE) had risen quite a lot so was tricky to get some foreground action in as well so the comet is tiny in the panorama. Neowise was easily visible naked-eye, even over the heavily light polluted city of Leeds. A Bit Of Everything. by Stuart, on Flickr Comet C/2020 F3 (NEOWISE) by Stuart, on Flickr

    Perhaps not as impressive as all those amazing images, but here's my sketch from 10.57Ut last night. In my 4" apo and with a 35mm Eudiascopic eyepiece the comet all but crossed the entire field of view. At high power using a 3.4mm HR eyepiece the nuclear region revealed nice structure.

    Had a go at stacking some images taken through my 10" dob this morning. There was a bit low light cloud around at the time. I think it came out alright though.

    Registax stack of 34 x 1 second images, Canon 450D at ISO400, Vixen ED 114 600mm, at 3.45 BST this morning. Easily seen with bins including a definite tail, just visible through the murk with the naked eye, provided you knew where to look. The twin outgassing structures were clearly visible in 6x30 bins. It seemed about the same brightness as theta Aurigae to me, which puts it at around magnitude 2.6, but this was only at an altitude of 8 degrees.

    These two panels were meant to be part of a larger mosaic that I haven't finished yet. I'm posting now because I've been playing with Affinity Photo, and I'm very pleased with the results. Previously, I wasn't able to balance up the colours in both halves at all. This version might not be to everybody's taste, but the balance between panels is much better than I have ever managed before. I've now purchased a full copy of Photo, and I will be using it in future. The left hand pane has 80m Ha and 100m OIII. The right side, 60m Ha and 130m OIII. @rodd's superb image has prompted people to ask where WR134 is, so I've highlighted it in the "finder" image below. The data was acquired last summer with a G3 16200, Tak 106 at F3.6, on an EQ6. Hopefully, I should get more data over the next couple of months so that I can extend, and do a more traditional RGB with the NB blended in.

    I've had a lovely evening with my old Skywatcher ED120 Started with some double stars as the sky darkened. Zeta Herculis, Delta Cygni, Izar, Epsilon Lyrae, etc, etc. The old favourites. Did try to split Antares as it peeked between a gap in the the nearby rooftops but it was a rather ill-defined, sparkling orange and blue / green spot so no joy with that. Then had a happy 45 minutes on the Messier globular clusters in Ophiuchus, M12, M10, M107 and M14. Some lovely settings amongst star fields with these, especially M12. Popped up to Hercules for M13 of course - fabulous view for just 12 cm of aperture - masses of stars resolved across the face of the cluster at 120x or so. With the sky quite dark now I had a look at M57 in Lyra and, as well as a really nicely defined ring structure, I could see the magnitude 13 star close to the nebula with direct vision. By now Cygnus was well up and just a smear of the milky way was showing through it so I sought my favourite Summer target, the Veil Nebula. I experimented with 3 eyepieces - 40mm and 30mm 2 inch 68 degree Aero ED's and the 24mm Panoptic, and 4 filters, the Lumicon and Astronomik O-III filters and the ES UHC and Meade 4000 Nebular Narrowband. Without a filter at all even the brighter Eastern Veil segment was virtually invisible. Swapping around eyepieces and filters I got the best results with the 30mm and 24mm eyepieces. The 40mm showed the most sky of course but the sections of nebulosity were just not as distinct against the lighter background. Of the O-III filters, I felt that the Lumicon was a touch more effective than the Astronomik tonight but both did a good job of teasing out both the East and Western portions of the Veil and the elongated chevron of Pickerings / Flemings Wisp in between. Of the UHC type filters I felt the rather old Meade 4000 Narrowband put in a better performance than the Explore Scientific with the ED120. All the filters made a noticeable difference to the visibility of the Veil nebula though. Without them, there was little to see apart from star fields. I finished my session with M27, the Dumbbell Nebula which had just risen above the trees. With this object I usually prefer the filter less view but tonight the UHC's just added to the contrast of the "hour glass" portion of the nebula and drew out the surrounding fainter halo that frames it rather well. A bight meteor that streaked down though Serpens and Scutum was a nice additional touch. I did wonder if it was one of the "Scutids" which is an active shower from 2nd June ? The forecast this evening was very mixed to say the least so getting a nice 3 hour session with my trusty ED120 was a real bonus

    An animated gif. 26 x 15 second images over a period of about 12 minutes. Canon 6d. 75-300mm zoom @ 230mm. ISO400. Tracked on a Skywatcher AZ GOTO mount. I wish I'd captured RAW files instead of JPEGs. Next time...
