    I’ve recently been getting into wide field night scape shots as something different to tracking deep sky objects, some nights it’s nice to just go out and snap away without having to polar align etc! Here’s 15 x 11s exposures stacked, the moon was just setting to the right and I was very pleased I managed to get Jupiter’s reflection on the water!

    Good morning folks, sorry about turning in early last night, seems I missed a lot of the action. Just had a look at my Pickering [OIII] data, which looked good so I've made a preliminary HOO with 4 hours each HII and [OIII] Cropped the alignment edges, DDP, Gradient Removal and a Colour Balance.

    Last night the challenge of seeing all seven planet in one night was once again on my mind. I started my session around midnight after spending some time fiddling around with the collimation on my dob. With the Moon lighting up the sky, the largest planet, Jupiter was my first target. Despite some poor seeing, I enjoyed the equatorial bands and the neatly spaced Galilean moons around it. Although not a planet, Comet Neowise was next to be observed. It has dimmed significantly since I last observed it. The core has a lovely green glow to it but the tail is much harder to spot but certainly still there. I felt a slight sense of loss for the bright comet that I've enjoyed observing and photographing so much in recent weeks. The dob was carried around to the front of my house to allow me to continue searching for the planets. Starting from Mars, I slowly star hopped my way into Aquarius, where I found Neptune. With the Nagler zoom, I slowly increased the power to reveal a tiny blue disc. I watch as it passed through the eyepiece, hoping to spot it's moon Triton but it was not to be. Another short star hop through Aires, led me to the other ice giant, Uranus. A slightly larger green disc was the reward this time. From ice giants to gas giants, after another brief look at Jupiter, I set my sights on Saturn. Who doesn't love this planet, even with poor seeing it's a special sight with it's rings. The sharp 10mm Delos showing some of the small moons floating around the planet, as well as brief glimpses of the Cassini Division. One final bright planet was awaiting my attention. Mars seems brighter every time I see it and has already shown some nice features in recent weeks. It was more of a struggle with the poor seeing on this occasion but none the less, the red planet became the fifth to be ticked off the list. I packed up and settled down for a couple hours sleep on the sofa. Rising at 4am with bleary eyes, it took me a moment to remember why I'd set an alarm. I looked out the window to see a fair amount of cloud kicking around. Not good. I grabbed the binoculars and began to scan the horizon. A break in the cloud allowed Venus to shine through and I quickly ticked this off with my binoculars and then my 80mm refractor. I began searching with the binoculars again, soon a golden point of light caught my eye in the binoculars...Mercury. I popped the dob out front quickly and enjoyed some quick views of the little planet before it was swallowed by cloud. On the 17th December 2018, I first saw Mercury and proudly reported that I'd now seen all seven planets with my telescope. One response to that report said words to the effect of "now you need to see them all in one night!". It seem far fetched at the time. Now after more than one failed attempt, I can finally report that I've completed the seven planet challenge!

    The 4mm DeLite has arrived! Great optics and appearance, sliding/locking eye guard, large eye lens, and 20mm eye relief - important for a specs user. The latter point - plus the lightness (300g, inc. 2" adaptor) are important to me, so I am happy with the 62deg AFOV, especially in a high mag eyepiece. Really keen to put it into action - report to follow. Doug.

    Lucky to get another night out using Sharpcap live stacking and my Altair GPcam3 290c. Telescope was again my TEC140 with a Meade 0.33 reducer (at about 0.4) so the scope was operating around F2.8. The globulars were 15 second exposures and the nebula 30 seconds all the stacks were 5-7 minutes in total except for M16 where I went for 15 minutes. They were saved as seen PNGs then tweaked a little in photoshop. The new camera has helped me fulfil an ambition to image the Pillars of Creation. M13 M92 M16 M27 M11 M71

    Been some time since I posted on here about my TAL-1 that I was going to strip down and refurb. Well here it is - got some before and after pictures for comparison... had many people say it looks like a old rocket launcher so thought I’d stick with the idea and go for military green colour! Definitely gave myself a hard task giving my first ever telescope, made in 1993 (I think) new life. Haven’t done the finder scope and there are some scratch marks due to lack of proper storage and I was missing a leg, which I got made, so some retouching is in order. But overall I’m very happy it’s finally in full working order! Gave it first light a couple nights ago. Turns out it has pinched optics. So need to get that sorted and make sure collimation is spot on, but I got some nice views of the moon, which was good enough for me! I gave Jupiter a shot and I think more accurate collimation is in order, but I’ll get there.

    I have been trying to collect data for this image for over a month. Now the Moon is up again, and I will have to wait at least 2-3 weeks before I can collect luminance. Therefore, I have decided to post this HaRGB image as the real end to galaxy season for me. I was surprised to find that my favorite part of this image is not the Fireworks Galaxy---but the cluster in the upper right hand corner. I am not a big open cluster guy, probably because my stars are never very good from a color standpoint. But in this case, that is not the case. I have included a crop of the cluster and am amazed by the group of grapes near the core. My question is how close are these stars to each other in this assemblage of 8 or 9 stars? They seem extraordinarily close. Is this an illusion? My focus/guiding/seeing could be poor and there really should be considerable space between these few stars. they should be points after all. Anyway--I find this little cluster of jewels to be very interesting. The other question I have is should I be patient and wait to collect luminance (5-8 hours is my goal). Not sure how much it will improve things and I have a feeling it will degrade the star color (and maybe profile too if seeing is not that good). As an aside....I have decided to tone down the intervening dust and gas that permeates this region of teh galaxy....my sky is not great and dealing with the noise resulted in having to live with a darker image than typical I think. Maybe with a lot more data this could be different. TOA 130 with ASI 1600 R: 34 300 sec G: 34 300 sec B: 40 300 sec Ha: 28 300 sec Cluster

    Certainly was no fun under the blistering heat and humidity of Cyprus. Solar imaging is postponed until autumn swings around. It's also the contrast-robbing heat plumes, not just the relentless heat! Not one of my best attempts, but still, can't be missing sunspots - a rarity during solar minimum. Lunt LS60SS, ZWO ASI178MM, Firecapture 1,500 frames, AS3! 20% of frames, a sprinkle of IMPPG and a dash of Photoshop! CS, Nicos

    For a few days, Clear Outside has been showing a few green squares for tonight. Then this morning: green from 11pm - dawn! At last - it's been weeks since I had a proper session. Still not properly dark yet, but getting closer all the time. I've got a new (to me) Aero 30mm 2" and I was desperate to try it. At 9pm, I was taking the dog for a walk. My son called to say his pals were going to come over for a sleep-over. Oh no - that'll make things more complicated. 3x15 year olds raiding the fridge all night. Then... clouds. Load of them. Thick dark clouds!!! Anyway, after giving strict instructions to the boys about the kitchen light. I set up my Bresser 8" Dob and crossed my fingers. It started to clear at midnight. A few patches, so I was going to have to pick my targets a little less randomly than usual. I started with Albireo - nice and sharp and the colour contrast was very clear. The seeing looked quite good, so I checked Mizar and the double-star split very clearly. So time for the new EP. I found the double cluster in Perseus first. It fitted the 68deg view perfectly. The small tight central parts of each cluster were well defined, with the stars incredibly contrasting and bright. A real high-def effect. The outer parts of the view were not so, unfortunately, but not surprisingly. So I just sat and admired the star-dust. Next was M31. It was obvious in the finder and didn't disappoint in the EP. The central core was there, but some nebulosity around it too - not quite stretching as far as M32 though. Still, much brighter than I had expected. M110 was barely visible with averted vision. The clouds were increasing now, so I had to move around. First view of Saturn! It has eluded me so far, due to obstructions in the garden, but tonight I found it (x100). Shimmering with little definition, but still an engrossing sight, so I stayed with it for quite a while. Jupiter was too low and hiding behind a wall. I'll need to find something sturdy to stand the dob base on. One last target, so I decided to have a shot with the Blinking planetary nebula. which I haven't seen before. Hard to reach as it was almost at Zenith, and the clouds were occasionally intruding, but I found it and commenced the averted vision trick. I couldn't see any colour, so the grey nebula kept blinking out of existence whenever I stared at the central white dwarf. A neat little trick, and hopefully more colourful when dark skies return. I find I like to write things up afterwards, to make sure I don't forget any part of the session. So I hope you excuse my ramblings. Quite a few firsts tonight. Boys are still awake!

    I got Plate Solving to work so I know how it to do that now. So much easier than I thought it would be! It sounded really complicated but it's so simple once you realise how to do it! Absolutely fantastic. No more Star Alignment and watching my mount slew to the other side of the sky then spending half an hour getting stars aligned and finding Deep Sky Objects. Bit of a dance with the clouds tonight but I'm glad to have got that working. A modified DSLR, first Narrowband Filter (for OSC) and Plate Solving all in one week. Nice! Good luck to anyone still imaging, and good night.

    Hi, This is M31 taken with the TS 76EDPH F4.5 refractor this month, so quite low, i had to dump a lot of subs and stacked 240 L's and about 85 subs of each channel RGB, all are 60 seconds. This image is the first light for both the scope and the HEQ5 pro Rowan.

    This is my Pacman from last night, in Hubble Palette, through my Quattro 8" at F3.6, which is a bit steep for me but I only have a 0.9 coma corrector at the moment. About 4 hours' worth, once I realised that the reason my Sesto Senso focuser wouldn't connect to my laptop was that I'd forgotten to plug it into its power supply. Schoolboy error which cost me half an hour! Hoping to get more on the same target tomorrow night. Cheers Stevie0

    Sorry to bore you folks, but I recently learnt a method of noise reduction in Photoshop on Astrobin (which I am happy to Share), It was posted by Roberto Colombari and you basically make a duplicate of your image, make it into a Starless image and then blur it, then place it back on top of your original image and blend mode lighten. This is what I tried out last night. The top image was 1 hours of Ha data processed. The lower image is the same processed image treated with the denoise method. I'm well impressed with the results, but it can smooth out the Nebula a bit too. I wasn't happy with some of the areas of my Cygnus Mosaic so I treated that to this method and selectively applied the denoised image and normal image together.

    You must be the most inoffensive person on SGL John - after me of course. The worrying thing is that I'm actually starting to like the idea of an luminous pink refractor. For less than £5.00 I could respray my Tak, which would give me the reassurance that no-one would ever steal it.

    Well my 4 part mosaic work was a bit of a disaster last night, I had decided to focus on getting some HA and OIII in, having already suffered already in my 2 part mosaic experiment with the difference in seeing conditions I thought it best to try a different approach and grab 4xOIII and 3xHa 600s subs (I already had 4 OIII and 1 Ha on the first quarter). After looking at Jupiter for a short while I started the scheduler going - my plan was to set it off then head out to a few local sites in the countryside to play with the sky guider. I was also going to experiment with Ekos Live to monitor the scope activities. Off I went to the first site to take some pics of Neowise, Ekos Live was showing the scope was still focusing as I left our road (passenger in car) and I set up, eventually found Neowise and spent quite some time shooting at 300mm. During which I thought I would check progress... nothing, no connection between Ekos at home and the server in the cloud... had the link broken between home and the cloud for some reason? Had the telescope Ekos crashed? My VPN decided not to work on my phone so I couldn't check, perhaps we have had a power outage? Wrapped up at Site 1 aroun 00:20 and headed the short trip back home to check. Ekos had crashed and left PHD2 tracking and the Indi drivers were still working so the mount was being guided but no imaging was happening..... a quick reboot of the telescope Pi and Ekos was back on schedule duty, this time I disabled the connection to Ekos Live (their site is beta, perhaps that was the problem?) and waited till it was capturing the first sub of the revised sequence before heading off the Site 2, a bit further away on the banks of the River Blackwater - my minds eye had a short of boats and masts with the milky way involved.... got there to discover that even through all the lights go off at 01:00, here they keep a load of lights on around the marina and sea wall, so the result was nothing working to the South - which is a shame! So I turned my attention to the East and captured some M45 & Venus with landscapes - lots of processing to do I think to get them all together. Biggest problem after the tripod weight meaning it was hard to keep PA when changing lens etc was also focus of camera lenses, very small window and lots of backlash to contend with on top of hard to see focus point, a lot of guess and mess with the live view of the camera and a zoomed in star! Enjoyable noise of squeaky field mice playing in the long grass next to where I eventually set up - they sounded like a herd of guinea pigs! Home for just after 3:30 to the relief the scope was still clicking pictures. Tried Ekos Live hilst last sub was coming in and performed fine, maybe it was something in the focus part that caused the problem earlier? Flats then in bed for just before 05:00. About 55 keepers from the mobile shots and 3/4 of the Ha and OIII I had planned on the mosaic were taken, probably one to chuck due to cloud... Fustrighting early night but OK in the end... The 3d printed adaptor needs more work but has some potential, the old HEQ5 tripod would have been better for Site 1 and luggable for Site 2....

    The colour of the scope was only small one part of the package of the scope that I linked to. The specification of the scope, the mount and it's price all added up to what I felt was a poor deal for the budding astronomer. If the price had been £25 then I would not have thought to mention it. I suspect that I've no chance of redeeming this thread though so fair enough. Apologies to those who I might have inadvertetly offended. As the saying goes, "the first thing to do when you are in a hole is to stop digging"

    Last week I ended up buying a pink fishing rod for my son, as it was the only colour left. He ended up catching just as many fish as I did with my black rod. (He’s only 4). I assume telescopes are the same. My epsilon is a daft yellow colour for example but works ok.

    First kit and I feel like I'm starting with the biggest setup I can own. Picked up from astrobuysell.com for £125 including a 40mm and 25mm Celestron E-Lux. Finder scope will be replaced with right angle. It has a Telrad mount (as I found out by accident) and I've alreadyt found cheap one on FB so should have that soon. Next pieces to get will be WA 6mm and 15mm. There's a small mark on the main mirror, but it doesn't seem to affect the view, and at that price I can't complain. The base also needed some attention. Vertical movement is smooth, but horizontal rotation was hindered by the bottom board being slightly bent, and rubbing the corners against the telescope base. I have added some washers between the teflon pads and it's much better. Not buttery-smooth, but I feel like that would make it too sensitive to movement, In the current condition it lets me track Jupiter easily. I guess the real test will be when I get the 6mm piece Collimating laser is also coming to make sure the mirrors are aligned after haling it home for 40 miles. Other than that it doesn't seem like it needs any serious work, so for a 20-30 year old telescope this is amazing.

    Hi all, I had a small window this morning (0800am Eastern Time) here in Florida before clouds & rain rolled in. It's now thunder storming of course. But in that brief period I had a chance to get some decent data on AR2767. The spot has evolved a bit and the plage has decayed to something smaller with less major filaments coming from the area. Being close to the center of the face of the disc in its transit, some features are more obvious now (like cells, and the structures in the penumbra and sometimes the inner structure of the umbra itself). The plage is less dramatic and mottling less dramatic straight on compared to at an angle where more contrast is on the spicules. But straight on like this, the convection cells and k-grains are a bit more obvious with better contrast I think compared to at an angle. I noticed the beginnings of what might be a light bridge were different in the various wavelengths, in HA it appeared to have a nearly complete light bridge in two sections of the umbra, but I didn't see that same structure in Gband, but the structure's root to the umbra was visible, however in CaK it was a little less visible. Kind off as I have not noticed that before (with a completed light bridge I typically note it in all wavelengths). So perhaps it was not a light bridge. I'm not sure, so I'm interested in everyone's thoughts on this phenomena! B&W: Colored: Animation of all wavelengths aligned on the Sunspot: Seeing Conditions (not great, but supported the image scales of 0.2" to 0.4" per pixel with sub-arc-second-seeing): Equipment: 150mm F8 Refractor + 2" Baader Red CCD-IR Block Filter (Sub-aperture internal D-ERF) + Baader GPC 1.25x (F10) + PST 1A HA Etalon + 10mm BF + ASI290MM + 2" Baader Blue CCD-IR Block Filter (Sub-aperture internal D-ERF) + 2.5x Telenegative Amplifier (F20) + EdmundOptics 430nm Filter + Baader 3.0 ND + ASI290MM + (aperture masked to 120mm F10) + 2" Baader Blue CCD-IR Block Filter (Sub-aperture internal D-ERF) + 2.5x Telenegative Amplifier (F25) + Lunt CaK B1200 + ASI290MM Very best,
