This is the first image that I am happy with since I started becoming seriously interested in astrophotography over a year ago. C&C welcome.

You forgot something

You forgot something

I accidentally hit return before I added the image. Hopefully fixed now.

I think it is very good.  The filter you used is a dual band for OSC cameras. I use an Optolong L-Extreme filter which I suppose is similar.  I suspect that if you process the data in Siril, you could separate out each band assuming they represent Halpha and OIII.  You could then use Siril to make a composite image like an HOO image. In this particular nebula it wouldn't make much of a difference per se, but it might give you more control over emphasizing one or the other bands.  In some other nebulas, doing this can make quite a difference from the regular OSC view using the filter.

Thank you for the feedback. I know GIMP isn’t ideal for astrophotography and have been experimenting with Siril but haven’t climbed far up the learning curve yet. I guess that should be next on the agenda.

The GIMP works very well in AP when used in conjunction with a program like Siril. I'm biased as they are the only two pieces of software, with the occasional use of RawThereapee, I use. Anyway, you'll get better with time and experience. You have a good start. Cheers.

Anyway, you'll get better with time and experience. You have a good start. Cheers. I have tried DSS, Siril, and APP for deep sky stacking.  Siril is the easiest and quickest.  APP is the best for stacking multi-session images taken with different scopes and cameras. DSS is OK but not as flexible as Siril. 

 

I capture my images with APT (Astrophotography Tools) although most people probably use NINA.  I just haven't learned NINA yet.  For some targets, not so much deep sky, I'll use SharpCap. I stack mostly in Siril.  DSS is OK.  APP (Astropixel Processor) is good for multi-session stacking using different scopes/cameras.  Also good for doing comets. 

 

For tweaking stacked images most people use PixInsight.  Some like Affinity Photo.  Some like Photoshop.  I like GIMP the best but like to use it with a touch of Topaz Labs De-Noise.   That is the only Topaz Labs program that I like, but you can't over do it.  For deconvolution tweaks, there is an interesting program mostly used for solar imaging but good for everything called ImPPG. I sometimes use PhotoShop Elements for color adjustment, but GIMP is the better program overall.  I sometimes use ImagesPlus for star reduction and star thinning.  I sometimes use Starnet++ which is now part of newer versions of Siril. I actually like the older versions of Siril better and use Starnet++ separately (when I use it at all). 

 

If you ever want to do time lapse of asteroids or comets or whatever, PIPP is good to know about.  It is also good to know about programs that do batch processing.  ImPPG is one of these. Siril can do that also but you have to be good at using it in that case.

Lovely photo.  Keep going!

Congratulations.  Good image.
