M45 LRGB PS NR

This is a reprocessing of my first LRGB image with my ASI1600MM-C. This is the same data that was taken over four nights with separate FLAT by filter each night. I used a gain of 76, offset of 40 and USB of 60 with the temperature of -15C.

71 X 120s RED
69 X 120s GREEN
59 X 120s BLUE
69 X 90s LUM
41 X 240s LUM

All the frames were restacked with PixInsight and had much better star regestration both for each filter and for matching and aligning the different filter master light frames. The 90s and 240s LUM channels were combined with HDR in Photoshop for a Master LUM. This worked a bit better than using PixInsight.

The R, G, and B data was combined in Photoshop as an RGB image. All the gradient removal and Inverse ArcSinh stretch was also done in Pixinsight.
Final sharpening and curves adjustments were done in Photoshop.
