That's an excellent result Humi.
Did the image progress much after say 15 hours though?
With noise reducing at.the.square root of the increase in time you get rapidly.diminishing returns. Some objects that are super faint seem to come alive
But a relatively bright nebula may not progress much.

I've never done that long on a single image so I am curious if there were benefits.
