Heart and Soul HaRGB

[mackiedlm]

This is my first every attempt at HaRGB with my DSLR.

There are clearly some issues; focus is not perfect on the HA frames I think - although in BYEOS they were showing ok even zoomed in hard. And there seems to be a bit of coma further out - not sure if thats just the lens or something else?

I've not done a brilliant job in processing and its quite noisy/grainy when zoomed in hard and I think I've blown out some of the brighter areas - I'll see what I can do on round 2. It also needs a good bit more integration time.

Any suggestions for improvement in capture or processing would be greatly appreciated

BUT - this was my first ever effort at this and I'm not ashamed of it! So;

Canon EOS 1100D, Pentacon 135mm @ f4
StarAdventurer mount
RGB 29 X 180s ISO 1600 (with Optolong CLS)
Ha 29 x 180z ISO 1600 (Astronomik 12nm Ha)
Stacked and initial processing in Astro pixel Processor, Final processing and combining of HA/RGB in Photoshop

 

Thanks for looking and any advice you can give

As an emission nebula I would have just stuck with the Ha filter and not worried too much with the CLS capturing rgb. CLS may not have done you many favours here.

Overall a great image for a first try with short subs. Keep going and don’t forget calibration frames as well as they will help with the noise.

So, I've gone back to this and tried again, this time combining the channels in Astro pixel processor.

I think its an improvement but would appreciate hearing other thoughts.
