M81

CGEPro/STL6303/AOL/MOAG/C14HD

LRGB 25X10s all channels. ADU @100 seconds hovering around 1400 which is a sad NYC sky.

 

Same data as previous.

More darks than last processing pretty much have settled on 100 being about right. Same stretching technique as M101. Other processing changes were that I separated into CMYK in photoshop and did noise reducion on separate layes, sharpeing only on K layer. Probably best to do this as color noise is more annoying. While not great, its a lot better then first processing, but it need more data.

Same data with more processing knowledge:
