Description

Most recent attempt at M33. I collected new data over two nights and improved the processing a lot compared to my first attempt. I like this one a lot more than my initial version, but I still have work to do. This would benefit from a good deal more time for luminance. However, since the moon is too full to collect more data at the moment, I'm making the best out of what I have now.

B

Clipped some of the background to increase contrast

C

Cropped and binned 2x2

D

Levels adjustment

E

Different crop and rotation

F

Reprocessed only the best subs using multi-scale processing to bring out the spiral structure.

G

Increased brightness of F

H

A little brighter than G. I'm still not great at getting the image that is uploaded to look like the one in PI.
