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

Thanks for that Bryan, I really appreciate it. 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.

Shawn from Visible Dark shows the process using his OSC and a L-Enhance filter.

@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.

Yes, the quickest method is APP, you can use Extract HA and Extract OIII algorithms and save these as individual files.

 

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.
