Description

M1 Crab Nebula false color image in SOH pallet. This is my first narrowband image. I like this combination as it has more of a pastel look. However, I lost the star colors and need to try to recover them. The target is fading, so there is little time or clear skies to capture more SII and OIII and some RGB for the stars.

On March 10, I acquired some more Oil and Sii data under non optimal conditions. I also refined my PixInsight processing and added flats. I finished the image in Photoshop with dodging, cropping and sharpening with a first attempt with the Shake Reduction filter.
