Popular Post Dmack1 Posted March 13, 2021 Popular Post Share Posted March 13, 2021 (edited) This is about 3 hours with the ASI2600mc and the L-enhance. A reprocess - stacked in APP with the extract Ha and Extract Oiii algorithms then processed in PI using the SHO-AIP script C&C appreciated Edited March 13, 2021 by Dmack1 12 Quote Link to comment Share on other sites More sharing options...
GazAstro Posted March 13, 2021 Share Posted March 13, 2021 Looks really sweet ! That's becoming a bit of a cult camera. 1 Quote Link to comment Share on other sites More sharing options...
Astrobdlbug Posted March 13, 2021 Share Posted March 13, 2021 I have perhaps said this before but I’m a real fan of this style of colour palette. I didn’t realise you could split out broadband channels with OSC and these dual narrowband filters. Really impressive image given short integration time Getting a ‘post-able’ - not a word ! - images with short integrations does seem to be a very attractive feature of this camera/sensor with its sensitivity and low noise - what telescope did you image with ? I’ve seen some other amazing images posted with very fast reflectors, the Epsilon paired with this camera - all very tempting but then again we are talking about nearly £5k of equipment - so perhaps not....must check lottery ticket Bryan Quote Link to comment Share on other sites More sharing options...

No Tak Epsilon here I'm afraid! This was with the Skywatcher Evostar 80ED doublet. I do think the camera is a bit special though. Quote Link to comment Share on other sites More sharing options...

Dmack1 Posted March 14, 2021 Author Share Posted March 14, 2021 (edited) @AstronomyUkraine I like a lot of Shawn's stuff but honestly I found that one to be unfathomable! I was unable to follow it - just too complicated. Basically all I did was to extract the Ha and Oiii in APP. Then normal linear processing, careful stretching of the Ha and Oiii, masked stretching of the Oiii to make the blue pop then combined in SHO-AIP, A lot less complicated than Shawn's way.

Now I'm on PI, I just get the RGB to the end of linear land, then split channels. Merge B and G using a method I found online to create the OIII. Save the Red as HA. Then combine into HOO, or SHO with a fake SII. Quote Link to comment Share on other sites More sharing options...
Astroarg Posted April 2, 2021 Share Posted April 2, 2021 This is a lovely capture.. this chip certainly grabs a lot of OIII... those blues are putting my 183 capture to shame haha! 1 Quote Link to comment Share on other sites More sharing options...
P Holdsworth Posted April 3, 2021 Share Posted April 3, 2021 Lovely image especially given the integration time. I use the same algorithms in APP to split out the HA and O111 from a dual L-enhance filter and works really well. I personally think APP is a brilliant piece of software 👍 Paul 1 Quote Link to comment Share on other sites More sharing options...
