CraigT82 Posted December 15, 2020 Share Posted December 15, 2020 Beautiful! For me, 135mm images of M31 are the best ? Love to see it in context 1 Quote Link to comment Share on other sites More sharing options...

Jkulin Posted December 23, 2020 Share Posted December 23, 2020 Dan, that holds so much promise, the star colours are lovely as is the detail, you might want to create a mask and enhance the galaxy with a bit more colour, did you shoot any Ha to add?

warwickshireastro Posted December 25, 2020 Author Share Posted December 25, 2020 @Jkulin Many thanks! I’ll definitely have to try a mask and tweak it. Want to add more data first. I don’t have a stand-alone Ha filter sadly but I do have an L-enhance and a modded DSLR. Not sure if that would add any Ha value? Quote Link to comment Share on other sites More sharing options...
Jkulin Posted December 25, 2020 Share Posted December 25, 2020 @warwickshireastro Hi Dan, No unfortunately only a Ha filter will be able to add that 1 Quote Link to comment Share on other sites More sharing options...
Astroarg Posted December 27, 2020 Share Posted December 27, 2020 @warwickshireastro yes it would, depending on what you use to process. The L-Enhance is HA/OIII at 26ish nm, so wide (similar to Altair tri-band)If you use APP, you can use the algorithm "Extract HA" to pull out only that data. You can then recombine this with RGB in any way you see fit (e.g. you could use the HA as luminance and have LRGB, or just use as plain HaRGB) 1 Quote Link to comment Share on other sites More sharing options...
