    Thin cloud caused some turbulence but during clear spells I had some nice views.

    With the addition of Mars my quest to image all the planets in the Solar system and our Moon took a step forward. All the images were taken with the ASI 224MC apart from the 2012 Jupiter which was captured using a SPC 900. Uranus is going to be my next target. Also I am claiming the Mercury transit as my Mercury for now

    Hi all, this is sh2-126 in Lacerta. If you locate Andromeda and trace a line towards Deneb it's about half way. This is a large star forming region approx 1200 light years from earth. The source of it's ionisation is the intense ultraviolet radiation of the star 10 Lacertae, a blue main sequence star. I had great fun collecting this data, on the first night I noticed what looked like a pinched mirror in the images as they came through so I had to perform surgery with the scope on the mount. I removed the primary mirror, loosened the screws on the mirror clips and put everything back together. The scope held collimation throughout which is a testament to how well built the Epsilon is. The battles continued on through the rest of the data collection with cloud, humidity and fog all adding to the fun, oh and not forgetting a lovely new floodlight my neighbour installed that points right at my scope. Data was collected with an Asi2600mc through an Epsilon 130. 6 Panels and a total of 24 hrs rgb with 10 hrs of Ha taken with a Samyang 135 and Asi 1600mm. If anyone is ever thinking of imaging this be aware it's quite feint and I found the image is nothing without the ha. Image is uploaded as .jpg and reduced to .5 to keep the image size reasonable. Hope you like it, Richard.

    Mars under not so good seeing very early this morning. Unfortunately blue channel in particular was impossible to get sharp but red was reasonable. 178MM with 250pds + 5x barlow.

    Hi. Interesting little Nebulae in Perseus,with a distinct comet shaped centre. This was taken with a 102ed at F6 and a Atik 314l+ mono ccd. It consists of 2hrs apiece in both Ha and O111. The centre is quite bright and really dominates its surroundings. I think i have a slight issue with guiding,as the stars are slightly off round. Cheers. Mick.

    ....but we won't see Mars as well as this again for a long time I think! Last night at 23:45 (22:45 UT). 2000/10000 frames with a 180 Mak, ADC and AS1224 colour camera, barlowed to ca. f24. The seeing was less than average, with frequent wobbles and shimmering. By eye, Olympus Mons was very clear, and it is visible in the image as well. I couldn't see Sinus Gomer at all visually, but it has shown up in the image after processing (Autostakkert, PS). The poorer seeing than a couple of nights before has brought up the dark artefact on the W side of Mars. I've pasted a Mars map from the BAA website for the same time next to the image. Chris

    The weather forecast was for clear skies this morning and on a whim I decided I will try for the elusive Sirius B since these years the separation is as large as possible: almost 11''. Sirius transits the meridian at 6:30am when its 21 degrees high - as good as it gets from here. I went outside at 6am and there were some high clouds but the southern sky was clear. Unfortunately Sirius itself was twinkling and I knew it was going to be a mission impossible. I used 9mm with my Skymax 180 giving 300x magnification. As I feared Sirius was a blob, dancing in rainbow colours and no sign of the Pup. I tried averted vision, moving Sirius just outside the FOV but nothing helped. Oh well... I wanted to make sure its not the optics, so I pointed at Rigel and saw the companion easily: a pale blue dot southwest of the primary, well separated, I think 10''. The companion of Rigel is magnitude 7, while Sirius B is 8.4 and lower in altitude so it's bound to be much harder. Well, I was up at 6:30am on a Sunday so decided to have some fun anyway and aimed for Alnitak. Last winter I tried repeatedly to split it with a Skymax 127 but never could. Today it was 'almost' easy: I had to wait for moments of good seeing and then it was visible as a yellow dot very close and south of the primary. Nice! It was getting light but the moon was almost overhead and looked clear. Using 300x I could clearly see the bow of Sinus Iridum and also some shadows on the floor or Aristarchus and Vallis Schroteri next to it. Definitely worth getting up early on Sunday! Further south the crater Gassendi was very nice with its central peaks. I could see a long line to the east it. When I came back I checked the Lunar Orbiter map to identify it - it was Rimae Mersennius. So I didn't see the Pup but still I had a good observing session. Very happy. Obviously have to try harder for the Pup.... Clear skies! Nikolay

    I do recall saying on several occasions that I was not into 'cartoon colours'. This comes close (in my eyes). As I processed the data it more or less just jumped out at me like this - of course I played with curves etc. to end up with an image quite colourful for my style.....but that I actually like too! It will go up on my web site later today - if anyone is interested in full details and higher resolution. (In brief: 8 hours Ha, 7 hours each SII & OIII...and then 3 hours of RGB thrown in.)

    Had a brief look at Mars tonight - before the only cloud in the sky obscured it !! It was very bright and I did notice that when the cloud started to obscure it the view got dimmer and more comfortable to watch. Takahashi FC100-DZ at x217

    Well, its been a couple of weeks before I was able to go out and grab some OIII for this one (always a challenge due to localised LP) - but its now in the bag and I've spent the morning processing it (still feeling pretty tired though.....lol). So, the million dollar question - can this lens make a pretty photo? Yeah, I think so Had to crop a little bit out because of a medidian flip on the OIII, but I didnt lose that much. While I was there I also topped up the Ha luminance layer for a bit less noise in the outer regions. One other note though... being as the lens body is almost entirely made of metal (and can hence get quite cold) - you do need to go out and adjust the focus after about 45 min from the session start... nothing unusual or different from any other telescope or lens really. 19x900 (Ha_L), 8x900 Ha_R, 8x900 OIII_G&B - Modified cannistra biclour process Askar ACL200, QSI6783, NEQ6 Thanks for looking!

    Finally observing galaxies again with my 20 inch dob after the rebuild. Observing galaxies in Draco which is well placed to the West. Two pairs stood out tonight. NGC 6285/6 (ARP 293) Both were relatively easy to spot in my 7mm eyepiece making a nice faint pairing. Here is an image of them from the internet. I also had a look at NGC6290/1. These were a little harder but stood out in the 10mm ortho lens and are to the left in this image. My new set up with a stronger mirror cell is helping as the stars seem sharper than before and this is helping pull out the faint objects. Really good to be back out observing. Mark

    Hi guys It took 9 nights between late August and early October, but I finally got enough data to complete the big mosaic of the Cygnus area i'd been wanting to do for ages. In a rare period of good weather, at one point there were 4 clear nights in a period of less than a week. Suffice to say, that was a rough week and by the end of it i was barely hanging by a thread due to the lack of sleep! I'm committing the cardinal sin here of posting late at night after spending hrs of processing (for about the 3rd night in a row) but i think it's finally time to stop looking at it and just post it lol. This was done with an Atik383l+ and two vintage lenses, a Tamron 135mm F2.8 and a Zuiko 50mm F1.8 - total outlay just £60 all riding on a HEQ5-Pro. The 135mm was used at F4.5 to do the 9 panels of Ha. Each panel is 108 mins (9 x 12mins). The 50mm was used at F4 to do a single panel of Oiii and Sii. The Oiii is 7 hrs of 20min subs, and the Sii is just shy of 4 hrs, also in 20min subs. APP used to put the mosaic together, which it managed flawlessly. PS used for everything else. I may end up downscaling it a tad, not sure just right now. Need sleep! Interested to hear what you guys think. CS. ps - It's a big image so be warned. The FOV is about 20 degrees wide!

    Last night was a night of exceptional seeing conditions, it made for some amazing views at the eyepiece even using my 3.5mm eyepiece, Mars looked razor sharp. It’s surface features were very well defined at 230x in my 115mm frac, unfortunately, my imaging prowess isn’t as good at faithfully relaying what I could see. Mars begged to be imaged last night, in this rushed image did I manage to capture atmosphere? it would seem so as I can’t explain the bluish hues visible on its limbs.

    The thing I learned a long time ago is to keep my setups very, very simple. Therefore I don't image, I just observe with a range of very simple, low or no tech, setups.

    In the couple of days since I last had a good view, Mars has rotated round a little and now the curved structure, hinted at previously, leading Mare Cimmeria was much more visible. The bright patch above the junction of Mare Cimmeria and Syrtis Minor was very visible and Sinus Gomer was again visible with the 5mm (320x). I think this is a sign the seeing was pretty good and the jetstream was missing me. A bright patch to the left of the N polar region was detected but not really resolved. The hook of subtle dark colour has advanced further round beneath the S pole and resembled a Nike tick almost. The SPC was very faint and if you didn’t know it was there you’d probably miss it! A fab night again for Mars Edit: the brightening to left of N polar region may have been Olympus Mons, though it should have been disappearing round the limb by the time i was set up. It was something i noticed first thing and couldn’t detect later in the session though so might have been. Will pay more attention to it tonight, weather permitting

    There’s a pub down the road from where i observe and very often someone, probably an uber, parks up for ages outside with his lights on full blast- pointed right at me! Other times street lights etc annoy if the orientation of the scope aligns. So i made this- hopefully it will do the trick. Cheapo knockoff Loc-Line jointed cooling fluid hose from ebay, a bit of bent aluminium sheet, and a bit of pvc sheet sprayed black. Bolted together and attached to ota with velcro, it’s an articulated nuisance light blocking flag. I’ll probably replace the pvc with thin alu sheet at some point but it needs to be light and i didn’t have anything else. Mark

    A rain washed sky gave some astounding views last night. The Milky Way was razor sharp which I studied as I dark adapted. A new (to me) observation was a nebulous like faint swooping connection between the spur (between Cyg and Cass) and the big hole just off Cass. This connection was a welcome addition to my MW observations. NELM, who cares lol! SQM? in the house. Bortle? forget that scale.The Milky Way is my guide for sky conditions now. A very good report by @Nyctimene had me wanting to explore an area I previously had not realized offered so much potential- the NGC 507 (ARP 229) group. What a rich, rich area to observe galaxies! The 15"/21E/10Delos provided great views- heres the list as I see it. I counted 8 galaxies seen but did not up the mag with the orthos to pull out more- this was just a fun session vacuuming up many targets, So: NGC 504, NGC 507, NGC 508/ NGC 495,NGC 496, NGC 499/ NGC 515, NGC 517. All were direct vision in the 10 Delos. Off for more! The Catseye nebula, NGC 6543 was its usual beautiful coloured self- did I see hints of its outer structure? The long lost friend, the Lobster Claw grabbed my attention immediately. SH2-157 showed more nebulosity in the area than ever before, there is a whole pile of it in this area, including the Bubble. More and more seen last night but I won't bore with them! The night was finished with a nice lawnchair observation of the Milky Way, a good night to it if you will.

    I've processed another video with the same setup. Here you have the result, beside an image from Mars Mapper (copying @chiltonstar's way of presenting) The blob I was referring above was Cerberus :-). I believe I did get an image of Olympus earlier that night, but I had way too much gain in my setup (and probably the seeing wasn't so good either) so it didn't come out too nice: Thanks for looking, NV

    Hi All So it cleared up last night and I got nearly 3 hours of useful data on M33. Most surprised for the UK weather at the moment just finished initial processing. might try tease a bit more out later, but I have other nights data on M3 that I want to incorporate as well. Any comments welcome as always. Thanks for looking

    Don't laugh, but tonight, for the first time, I tried sketching while observing. I have to confess that I am to Art what Attila the Hun was to World Peace, but for a while I've wanted to try to capture something of what I see through my scope. So I bought myself a little observation book off Amazon, sharpened a pencil, and went outside to look at Mars tonight. The sky wasn't too bad at all, varying during the hour and a bit that I was out from pretty good to fair seeing and back again, with a bit more cloud evident by the time I packed up at almost 12.30am. There is a lot of moisture in the atmosphere at the moment. I spent the whole hour looking at Mars with my Tak FS128 and a Revelation binoviewer, loaded with a pair of Morpheus 17.5mms and also a pair of Celestron Halloween 26mm plossls. I also used a Baader 2.25x zoom Barlow for higher power, and the sketch on the right was made at lower power, and the one on the right at a bit higher power. Both pairs gave nice views in moments of steady seeing, with the Morpheus pair delivering a much bigger fov and larger image. I have no idea what were the features I was looking at, apart from the southern polar cap of course, I will try to look online in the morning to see if anything was vaguely recognisable! The dark land mass on the southern hemisphere of Mars was by far the most prominent feature while I was looking tonight, and it "came and went" with the varying shimmering of the atmosphere. I found it very awkward at first, sitting on my Nadira observing chair, looking into the binoviewers (without glasses on), then scrabbling for the pad and pencil and then trying to put something on the page (with glasses on this time!) without dropping everything on the lawn! It really made me appreciate the skill of dedicated and experienced planetary observers like Mike (@MikeDnight).. Hopefully as I gain a bit more practice it will begin to feel a bit more natural.. I did quite enjoy it though, and will try again on a better night of steady seeing . Dave

    I was away for the weekend down on the South coast not far from Folkestone, with a very nice decking area facing the sea. Whilst there was patchy cloud around today, I still managed to grab an hour or so on and off observing the Sun during the clear spells. I was using my trusty Tak FC100DC on a Scopetech Zero Mount and Gitzo tripod which makes an excellent grab and go setup. I use a Baader Coolwedge, with Mark IV binoviewers, and 25mm Zeiss Orthos which are converted microscope eyepieces and very sharp. To get to higher powers I use a x1.7 GPC and an AP Barcon so today I was at around x100 (on better days I often go up to x200). Finally a Baader Continuum filter helps to bring out the detail, particularly granulation and faculae. The seeing seemed pretty good; granulation was immediately obvious across most of the disk and, given the current quietness of the Sun, I was pleasantly surprised to see some activity quite central in the lower part of the disk. It was quite fine, no large spots but two groups, one very compact and the other quite complex with a series of tiny spots and pores. There wasn’t much in the way of faculae visible today but still, good to get out there in such a lovely place to observe. Photos to show the setup I was using and the active area which is identified as AR2775. I couldn’t see anything at the position of AR2774. As normal, the views were sharper and with more detail than shown in the image.

    Finally managed to finish off the mods to allow me fit the Starsense phone holder to my OOUK Dob mount. Was hoping to get to try it tonight. Clear skies when I finished up and put the Dob outside. Just been outside and it's horizon to horizon cloud, grrrrrrr.

    Hi All, Here you have my try on the subject. Despite taking the image at sea level without an ADC, I'm quite happy about how it came out. Now I'm trying to identify what can be seen by using maps I've found in the Internet, but I'm rather confused. Syrtys Major is quite evident, as well as Mare Cimmerium, but is it Olympus Mons the blob that you can see at Tharsis?. If you know of a proper map I can look at, please do let me know :-). The gear: Celestron CPC 800 GPS XLT GSO 1.25" 2.5x Apochromatic Barlow Lens Risingcam GPCMOS01200KPC The software: ToupSky (4 minutes, 11 gain and 0.45 ms, which allowed to get up to 114 FPS) Autostakkert (30%, drizzle 1.5) RegiStax winJUPOS (for De-rotation and compensation of field rotation in altitude) Fitswork The Gimp Thanks for looking, NV

    Hi all. A break in the rotten weather the other day and fortunately had the opportunity to get set up in plenty of time. That said, I went in for a while to give Mars time to rise pretty much to the meridian and although the sky had been clear and the forecast good, there was a shower which fortunately wasnt too heavy. No harm done, the scope was only elevated about 20 deg at that point and the cap was on. Fortunately I'd also closed my kit box and closed the laptop. The seeing looked pretty poor - I had a nightmare getting focussed - and it was petty blowy. I'm sheltered from the wind by a high bank which is a disaster for views to the East, but great as a wind break, so the scope didnt get too battered but the image looked plenty wobbly. As it happend though the result was pretty good - best yet I'd say. Used my experimental scope - F4 250mm Quattro mirror mounted in 250mm Flextube scope with Omegon Velox 385C camera mounted at prime focus. I did white balance at capture this time because the RGB peaks are quite different and I wanted to be sure to avoid clipping. Getting quite used to the Toupsky capture software now. The best result was using 3x 6 minute back to back AVIs at 8ms giving 165FPS, giving about 178,000 frames. The gain was ridiculously low - I thought I'd done something wrong! AVIs joined in PIPP, best 25% then through AS!2, best 6%, then put the sharpened conv file through PS. Very pleased with the result, after quite a bit of testing the Omegon 385C gets a big thumbs up from me. Happy to receive comments as ever, thanks for looking. One question - does anyone know what AS!2 does to produce the conv file? I cant get anything as good using Registax wavelets.

    A simple way to check for atmospheric or local thermal effects on seeing is to focus on a bright star and defocus it to spread out its light into a circle. Is the circular image nice and steady or does it wobble and constantly change? If the latter, you're never going to get sharp images at high powers. I'm not saying that is what is causing your issue, but it can be easily diagnosed and eliminated as a cause with this technique.

    The last time I had a go imaging Mars was more than 10 years ago (with decidedly poor results)! Since then, I had a long break from astronomy and since returning to the hobby have focused almost entirely on visual observing (my ASI120MC-S camera has been used a total of twice in the two years I've owned it). Anyway, I decided I had to have another go at Mars given the current opposition and here's my first attempt at processing data from last night's run. I'm immensely chuffed as this is by far the best planetary image I've taken (although still far shy of some of the incredible ones I see here on SGL). Taken around 1am last night, through the C8, with Celestron X-Cel 2x barlow, with the ASI120MC-S. Best 20% of 10000 frames stacked in AS3! and wavelets applied in Registax. Also tweaked the histogram a bit in Registax to adjust the brightness. No other processing so far, although I'm hoping to use this data to learn more about the processing side of things as I have no idea what the majority of options in both AS3! or Registax actually do! I also still have quite a bit more data to process (this is from 1 of 8x 10000 frame runs that I captured) so may be able to improve it further. I loosely followed @JamesF 's guide to processing here: https://stargazerslounge.com/topic/184821-beginners-guide-to-stacking-planetary-images-with-autostakkert2/ If anyone has any ideas on anything else I should do processing wise or links to other good tutorials I'd be grateful.

    Hello. All things being equal then bigger is better. It has more light gathering ability. Which is always better on the fainter DSO. But bigger also can be more problematic in lifting , travelling, setting up in general. I have a 14" and a 8" and finding lately I am using the smaller scope more due to the practicality of the scope. The best scope is the one you will use. So if you have no problems with handling the 10" then go with that, otherwise the 8" is a great all round aperture for most. Hope this helps

    We will soon apply a significant update to the SGL platform but before we do we want to remind everyone what SGL is, and is not. This is important because it underpins the way SGL is constructed and moderated. What is SGL? SGL is a positive, safe, friendly online community where you can discuss all things astronomy with like-minded people. Whether you are beginner or professional, visual astronomer or astrophotographer, armchair astronomer or cosmologist. SGL is for you. SGL is not Facebook. SGL does not amplify negative emotion, does not insert dodgy video into your timeline and does not lock you in. There are no fake members or bots. No fake news or click-bait. You are not wrapped in a filter bubble then sold to advertisers (our sponsor pays the bills). At SGL your worth is not determined by how many followers or 'likes' you have. So if you enjoy drama, dissent and controversy. If you enjoy discussing politics and social injustice. If you enjoy constructing carefully worded insults. If you like sharing photos of your cat or breakfast. SGL will not suit you. SGL does however have a Lounge area for non-astro discussion. This is separate and distinct from the astronomy boards. Please help us keep it this way. Best wishes, SGL ADMIN & Moderators

    While the AZGTI was doing its thing with my scope on the Pacman nebula i set the star adventurer going with my A57 and an old 50mm Minolta f1.7 lens @f2.5 in the Cygnus area. Captured around 1hr 8mins worth of 30s subs at 800iso, captured darks and flats also. Stacked in DSS and processed in Startools, Topaz and paint.net I think i have captured a few objects in this frame. Thanks for looking Annotated:-

    Same here - no photos or equatorial mounts, although I do confess to liking the occasional use of GoTo since polluted skies make it hard to get started sometimes, and tracking is a boon, especially when you've gone up to higher mags. And - re the original question - Yes. Some sessions can fail dreadfully. But the good ones more than make up for it! Doug.

    It helps to remember the three "C"s: --Collimation. what tools are you using for collimation? how are you doing it and in what sequence? Do you check the results in a star image? Remember, it will have to be done every time you set the scope up. --Cooling. Are you running the fan on the mirror all the time you observe? it can take a large heavy mirror like yours a few hours to cool down to the ambient temperature, and until it is at ambient temperature, the images will be poorer, especially at high powers. Put the scope out at sunset and let the fan run. when you start observing later, the images will be much better than if you just set it up and zoom to high powers immediately. --Conditions. The steadiness of the atmosphere is all-important to get clear and sharp high power images. This will vary from night to night. First, reduce the "local" seeing problems by setting up on grass or dirt instead of concrete or asphalt. Heat will rise from the hard surfaces all night and ruin the high power views. Don't look at a planet right above a rooftop. Roofs release daytime heat most of the night and cause turbulence in the air. Don't look at a planet below 30° altitude if possible--the air is twice as thick at 30° as it is straight up and it is 10x as thick at the horizon. If you must look at something low in the atmosphere, look at it when it crosses the N-S meridian in the sky, where it will be highest. And be aware that when you look through a lot of air, you will also be looking at a lot of dust, smog, and water vapor, not to mention a lot more atmospheric turbulence. Use a shroud on the scope to keep your body heat from drifting into the optical path of the scope. Start with low powers and slowly work up to the maximum power that yields a clean sharp image, above which the image becomes blurrier. That point will be different from night to night and even from hour to hour. In most places, the seeing settles down after midnight, though that is too late for Jupiter and Saturn. But it will be ideal for Mars. and Mars, being farther north in the sky, will rise much higher. i think it sounds a lot like the atmosphere just wasn't steady enough for high powers. On your scope, low powers are 48-120x (32-13mm eyepieces), medium powers are 120-240x (12-7mm eyepieces), and high powers are 240-360x (6-4mm eyepieces), and above that "thar be dragons", i.e. the number of nights you will be able to use and magnification up to the theoretical maximum of 720x will likely not exceed 1 or 2 per year.
