  1. So, 6 nights, just over 9hrs of data, many hours going around and around with the processing and we finally have an SHO Rosette Nebula. This project was exhausting and Ive still got alot to learn across the board but for now, considering I only picked up the new camera in February, I'm happy! You can get stuck on those amazing images from very talented people and continue to feel like your getting know where or you can enjoy your own journey. If I'm honest, I still do both but what that does is give you an healthy shove to keep trying to improve. SW80 ED DS PRO at 480mm (x0.8 reducer), tr

  2. M108 is a spiral galaxy 46 million light years distant in Ursa Major. It is inclined at 75 degrees from the viewers perspective, so the spiral structure is hidden from view. Visually it appears as a relatively small object (11.1’ x 4.6’) with an apparent magnitude of 10.7. Its core is estimated to contain a supermassive black hole with an estimated mass of 24 million solar masses. I was pleased to capture quite a bit of detail on the galaxy including the Ha emission areas. The background also contains many small, more distant, galaxies. The LRGB image below was taken with my Esprit

  6. I had some data lying around that I hadn't processed properly, due to issues with dust bunnies. I made some new flats, and that seems to have sorted the dust bunnies out,although there are still some issues with gradients. I added the data to a set of 2h 45 minutes I gathered earlier, and there is indeed some imrpovement, although I still need far more (and better) data to be satisfied. Stacked in APP, colour denoising in FITSwork, curves and crop in Gimp. All data acquired with my Meade SN6 6" F/5 Schmidt-Newton, and ASI183MC (non-cooled) camera. Next winter I will have a go with

  7. The Lobster Claw Swimming in to my telescopes view during clear spells in the first few weeks of 2021. Some cold nights with large accumulations of snow on the hillside added shoveling to the set up routine, the temperature getting down to a respectable minus 14. Aswell as the main object catalogued as Sharpless 157, a pretty open star cluster can be seen in at the lower right claw ( NGC 1750) with Lyn's bright nebula seen up at centre left. This huge space crustacean in Cassiopeia is 11050 light years away and was captured over 4 nights. 19 hours in Sulpher, Hydrogen and Oxygen

  9. Hi! This is my first post here in a place besides "Lunar Imaging" lol I am somewhat of an odd duck in our hobby I think. I arrived to it via photography, and a chance shot at the moon I was amazed by with my DSLR gear about 5 years ago now. Ever pursuing better results, I dove into astro gear a couple years ago... scopes, mount and planetary cams. But... because I am somewhat lazy, and very busy with family and work.... and very light polluted in my neighborhood, I just never pointed my scopes anywhere but the moon - and planets now and then. Till now. This past week, I took d

  13. Well it was clear from midnight above us in York last night and it was the first chance to have a proper look around with the 8inch dob. Went outside, copy of turn left in hand with all intent and purpose to find somethings for us as beginners to view. I never picked the book up again last night. Started at Orion Nebula and after viewing that just spent the next two hours just looking around in amazement at the night sky through the scope. with 26mm eyepiece in all night I just kept staring at the night sky. I know and slightly regret I didn’t focus my energy in finding objects to

  14. This was the first test with the ASI 6200 and before I got the FF spacing and tilt optomised so excuse the stars on the right which aren't very nice. I was going to redo it once I'd got the adjustments better but it's sunk too low now. Thought it's worth showing though. FLT98 with FLAT 68III flattener, ASI 6200MM, Astronomik Deep-Sky RGB, and L-3 luminance filters. Stacked with Astro-Art and processed with StarTools binned 2x2. Just over an hour each of LRGB so a bit noisy in the background but am impressed with the 6200 which doesn't exhibit the blotchy noise often seen with CMOS came

  16. I fully appreciate I am amongst some amazing solar imagers here, but here goes. Whilst clearing out the shed Saturday 13th March I set up my old 3” frac and did some solar projection and managed to see a sun spot, ignore all the marks on the old plate, it was definitely there. Can anyone confirm.

  17. Heya, AR2808 is an interesting region, in HA it has a nice extensive plage and has filaments between the poles, but in the photosphere it's a tiny pore with not much else to see. Mean while, a smaller region that is now AR809 emerged and has a much smaller HA representation with a tiny plage and the poles are close together, yet in the photosphere it has a much bigger spot that is developing rapidly this morning (maybe it will grow larger and the poles separate a bit more to become a bigger region). It's a really great representation of the difference between the chromosphere and photospher

  19. I have spent an absolute age redoing my Rosette image from a couple of weeks ago, this time processing completely in PI rather than APP and adding 1 more hour of 03. I also replaced the stars in this narrowband image with RGB stars using starmask and pixelmath following a YouTube tutorial. I only had 5x30s for each of the RGB channels so not really much of an improvement to the image overall, but the whole exercise has helped me learn quite a bit more about PI so worthwhile so the same. This is 5x1200s Ha and 5x1200s O3, with 5x30s each for RGB for the stars. 200/1200 newt, at

  20. GEMINI NEBULA NGC 2371/2 - (ap. mag 11,2) This image confused astronomers when it was first studied — rather than being classified as a single object, it was instead recorded as two objects, owing to its symmetrical lobed structure (known as NGC 2371 and NGC 2372). These two lobes are visible to the lower left and upper right of the frame, and together form something known as a planetary nebula. (in:Nasa) To me it looks like a candy, to my wife like an eye and to many people like a peanut. At the end what matters is that you let flow

I was hunting with my Optolong L-eNhance filter and SW200P reflector to give me this chance beginning of March. A tricky target but I'm glad to say, 'I got one'!!! I hope you appreciate my efforts.

  23. First up is an old friend, Arp 148 in UMa. Not the easiest of targets to view. Its to the right of centre in the wide shot. It is a classic example of a galaxy doing a direct hit on another one. This pair are known as Mayall's object and lie about 500 million lyrs away. The offending galaxy has gone through the centre and is now heading out the other side. The shock wave creating the ring. Search out Hubble's image for this pair. Arp 336 in UMa - NGC 2685 takes us to the nightmare of galaxy designations - it is (R) SBO^ / pec (Sy 2) = outside ring, barred lenticular, messe

  24. So you have EQ6 and C5. That is what we know so far. What camera are you using? Are you guiding or not and if yes - how? What is your processing workflow and what is typical total exposure time for your images. What is light pollution level at your location (you mentioned garden exclusively)?

  25. I agree to powering the mount separately, even though the (Pocket Power Box?) can provide a total of 10A - given a suitable power supply. The simplification of just one cable up to the OTA - assuming ASIAir/Pro and PowerBox are on the dovetails - makes it easier to swap rigs. Allows you to have e.g. an SCT with ASIAir/Pro, powerbox etc attached, remove, leave all cables in place, transfer to, say, your refractor with it’s own cabling. You could also have an ASIAir/Pro, powerbox etc. on each OTA - at a cost

  27. I've joined the club, and tonight was the first chance to use the SW Startravel 80 in anger. Clear Outside had been promising clear skies all day and at 11pm the clouds vanished and I saw stars for the first time in weeks! I had the new scope and the dob out cooling for an hour already. Firstly, a star test on Polaris. Hmm - very odd shaped stars. Having watched Astro-Biscuit's latest video, I recognised pinched optics and tried to loosen the lens cell. Jammed tight! I had fiddled with it earlier in the week, when I had heard the lenses moving when I tilted the scope - tightening the plas

  28. My preference is to always power the mount separately, keeps it down to a single cable to the OTA This ensure that if you are slewing and the dew heaters come on you reduce the overall demand on the PSU feeding the power box. Generally speaking power boxes suggest 12 5A supplies, although Pegasus do recommend 12V 10A for their newest product.

  29. I have been blessed with four nights of cloudless skies over the past week so I have taken advantage of them by capturing M51, despite the blustery conditions. Generally I am very happy considering the size of the scope that I am using to capture this. This is made up 4.5 hours of luminance, 2 hours of Red, 2 hours of green and 2.5 hours of blue. Taken using a Meade 6000 80mm APO, HEQ5 (belt mod), ZWO 1600MM It is 10 months since I purchased my deep sky rig and M51 was one of the first targets that I imaged, albeit with a different scope and using a DSLR, and I have inclu

  35. First night last night with the AZ GTI setup properly in EQ mode. What a difference!! Must be something wrong with my alt axis. In az/alt mode i couldn't even get 10 second explosures - big jerks randomly, etc - and I'd taken it apart and rebuilt it with no improvement. Now getting 30 seconds easy - didn't try and longer but hopefully can. 100 subs with no duds is a first for me. Yes, these are terrible compared to the amazing pics on here, but it's a steep hill!

  37. For planetary observation I like to be able to adjust precisely to seeing conditions. I use parfocaliser rings on the Delos 6 and 8 mm eyepieces so they match the XWs. On my C8 at F/10, I like to have closely spaced EPs to fine tune the magnification to the seeing. I would love to insert a 9 mm between the XW10 and Delos 8, if truth be told. I certainly find the jump from 203x with the XW10 to 290x with the XW7 too much. The 254x offered by the Delos 8 very handy. Under good conditions I can even use the 6mm at 338x, especially on Mars and the Moon. The XW5 is more useful in my faster scopes.

  38. That's actually a decent image for just 10 x 3 minute subs. I'd imagine vlaiv would say the colours are good here (good = natural). However, many imagers (myself included) are guilty of pushing the colours a bit to make pretty pictures. The easiest (and cheapest) way to improve the quality of your images is more integration time. The image below was taken with a 50mm guide scope, but is several hours of integration time, so more aperture is not necessarily needed (granted it was taken using a mono cooled astro camera, but the same principle applies to a DSLR)

  40. Some folks reverse the barrel to avoid the snagging by compression rings in the focuser tube / diagonal. You can't do it with all eyepieces though. If Omni 9mm was purchased new it may simply have been screwed on the other way around by the manufacturer.

The pitches are available on first come basis. BUT, at present I cannot say for sure if it will definitely go ahead due to the ongoing Covid-19 Pandemic! All I can say is book early to ensure a pitch. If all goes to plan the Scottish Premier Star Camp will be held on the dates posted. It will depend upon the Scottish Governments decision on how many pitches are/will be availa

  45. I think that these days it's impossible to watch the night sky for more than a few minutes and not see a satellite. They're everywhere! Every single time I'm using my guide camera to polar align I see a satellite pass through the field of view. The area towards the Pole Star sees a concentration of Polar Orbiting satellites as their orbits converge over the pole. In the lighter months the sun's light reaches far over the horizon at those orbital altitudes even at midnight so they can be quite dazzling! I remember a time when I'd be excited to see a satellite. Now they're a nuisance!
