Astrobdlbug Posted September 6 Share Posted September 6 (edited) Update : noticed when platesolved I also have the dark nebula B150 in the FOV - known as the Seahorse nebula, so another animal to add to the zoo... Past two nights have been clear(ish) in my area, albeit with high humidity , relatively poor transparency plus a moon still hanging around - I didn't really have high hopes that I would end up with an image. However I kept the plan going over the two nights and captured 12 hrs of data using Samyang 135mm with Optolong L-Extreme and ASI2600MC. I processed the resultant 144 subs this afternoon and added a bit of old data from 2020 again using Samyang 135mm but with ASI1600 and Optolong 7nm Ha, Oiii, Sii filters, that was 4hrs of colour/luminance added around IC1396. I am really happy that I caught the squid - I didnt have to push anything hard on post process stretch, I just used GHS for stretching and little local colour saturation on Squid to give it a little more impact. I have substantially reduced the starfield otherwise it just becomes a sea of stars.

mightymonoped Posted September 6 Share Posted September 6 That’s a fabulous field of view Bryan. Great image and processing. Was the Samyang wide open at f2? Tony 1 Quote Link to comment Share on other sites More sharing options...

Tony, thank you - as usual with me the FOV was a bit ad hoc , when I set up the plan initially in ASIair and centred on sh2-129, the infamous squid I realised I could bring IC1396 into the FOV - this was the result. I should plan better with Telescopius 🧐 And yes Samyang opened to f2 Bryan 1 Quote Link to comment Share on other sites More sharing options...

TerryMcK Posted September 20 Share Posted September 20 I was looking at the Apod for 17th August 2023 for the same subject and Bryan I think your version is much, much better than the one that won that day. 1 Quote Link to comment Share on other sites More sharing options...
