Description

This is my second take of M1 with my celestron edge 8 at f/7. Much better guiding compared with the previous week. I am loading it as a new image, since it's not really a revision of the one I published earlier. 

Calibrated, stacked, light pollution removal and star color calibration using APP . Pixinsight for curves transformation, and final processing (cropping and minor touch-ups) with adobe PS. No additional noise reduction. 

Enjoy and critique!

Title: Revised image adding Ha and OIII data using L-Extreme

Description: I added 4950s/55 subs at 90s using the Optolong l-extreme filter taken February 8. Reprocessed and combined the RGB, Ha and OIII channels using APP. Credit to the blog below. I think it's a bit better than the original. What do you think?

Description: Used a different approach for removing some of the noise. Applied PI TGVDenoise chrominance protecting the core of the nebula with a mask. A colleague AP recommended it. Do you like it better?
