Crab Nebula M1

[discardedastro]

Alright, so a very limited dataset (bit of a theme of mine lately as I go hunting for new targets - I think this one's going to get some more hours) - total about 59x120s for a total of about 2 hours imaging time on my 200P/183MM-Pro/EQ6-R setup, mostly shot over warm rooves and relatively low down.

Processed with PI; the usual manual processing steps I do (cal, cosmetic fix, subframe selection, alignment, stacking, crop, DBE, linear fitting, channel combination), but I used R/B/L as a superluminance given the small dataset (green was unfortunately badly focused so ignored it). DBE'd a second time, masked using a range selection to denoise and selectively saturate the nebula (ideally wouldn't have oversaturated the stars but here we are) before LRGBCombination and final PCC/denoising.

Making the best of poor data! I think it came out pretty well all things considered.

I like it! Nice colours.

I'm disappointed with my efforts on M1 this year. Mostly due to equipment problems and weather.
