Popular Post Astrobdlbug Posted August 13, 2021 Popular Post Share Posted August 13, 2021 (edited) All. had only 2 hrs on this last night - I didn't think there would be anything to post with such a short integration time, but the ASI2600MC sensor is unbelievable. I brought my At106EDT refractor out for this one with 0.75x reducer/flattener. I did a real Heath Robinson job to get the Optolong L-Extreme into the optical path - I used its packaging foam jury rigged inside the OAG to hold the 2" filter in place ... but it worked !!! I got my OAG setup and reducer back spacing and it all worked , an imaging night when the gremlins stayed away, Kstars/Ekos also remained stable and guiding stayed consistant around 0.9 arcSec RMS error. Integrated in APP and processed with Photoshop today, using the APF-R plugin to give some sharpening, but no noise reduction used - I was amazed that none was needed. I am hoping to get 2hrs on the Eastern Veil this weekend and create a 2 panel hi resolution mosaic of the complete loop 60 subs 120s (2 hrs) Gear AT106EDT refractor 0.75x Riccardi Reducer/Flattener ASI2600MC-Pro Optolog L-Extreme Dual band filter Bryan Edited August 13, 2021 by Astrobdlbug Increased overall level to increase brightness 11 Quote Link to comment Share on other sites More sharing options...
Padraic M Posted August 13, 2021 Share Posted August 13, 2021 That's very cool for 2 hours. Looking forward to the second installment. 1 Quote Link to comment Share on other sites More sharing options...
ApophisAstros Posted August 13, 2021 Share Posted August 13, 2021 Looks good , alyhough a bit dark , perhaps just my monitor? Roger 1 Quote Link to comment Share on other sites More sharing options...

I wil investigate...... Done - you were correct it was too dark - hopefully this is an improvement -I've edited original post and changed link on astrobin to FINAL - as if.........

AstronomyUkraine Posted August 13, 2021 Share Posted August 13, 2021 Incredible for only two hours of integration. The mono version has the same sensor, definitely one to look at. 1 Quote Link to comment Share on other sites More sharing options...

For UK skies this sensor is certainly compelling to give astroimagers a good image in one night Bryan 1 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted August 14, 2021 Share Posted August 14, 2021 Excellent work, a great start for a mosaic. 1 Quote Link to comment Share on other sites More sharing options...
peter shah Posted August 14, 2021 Share Posted August 14, 2021 The 2600 is just phenomenal ....I love them. That's a wonderful result. 1 Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted August 15, 2021 Share Posted August 15, 2021 A great image. I shall have to invest in a 2600 myself 1 Quote Link to comment Share on other sites More sharing options...
paulgrover68 Posted August 15, 2021 Share Posted August 15, 2021 (edited) Nice work - I love the veil and have to fight the urge to shoot it every session! Edited August 15, 2021 by paulgrover68 1 Quote Link to comment Share on other sites More sharing options...

I thought about the option of the mono version, the ASI2600MM, but it is about £500 more than the colour version and then you need 2" filters and 2" filter wheel - the number just got very high very quickly. So I guess what I am saying in a rather long way is that its potentially not just the camera to invest in 44 minutes ago, paulgrover68 said: Nice work - I love the veil and have to fight the urge to shoot it every session! Thanks Paul - I only 'discovered' the veil last year when I started narrowband imaging - I had seen images of western Veil, Eastern Veil, Witches Broom, Pickerings Triangle, but never really put them all togther in my head as the supernova remnant , the Cygnus loop, that they are all part of, its 'wispy' entanglement just draws you into the image -so I am like you its a goto object in same way Horsehead and Gt.Orion nebula are in winter.

paul Posted August 16, 2021 Share Posted August 16, 2021 (edited) A great image. The balance of light n dark looks pretty good to me. It was images of the veil that convinced me to dive in to a mono setup. But I am impressed with what a modern colour sensor can achieve. With clear nights seemingly getting rarer your 2600MC is proving a wise choice. Edited August 16, 2021 by paul 1 Quote Link to comment Share on other sites More sharing options...

The penny has just dropped for me too - I never knew that the Veil was a supernova remnant. 1 Quote Link to comment Share on other sites More sharing options...
Dmack1 Posted August 19, 2021 Share Posted August 19, 2021 That is a super image - all the more so at only 2 hours. Just adds to my angst at having a 2600mc sitting on my shelf while the cloud gods toy with me 😭 Quote Link to comment Share on other sites More sharing options...
