So check this out. This is using the built in bin feature in Startools that I rarely ever touch + 6 more frames using dithering. I would say a drastic improvement.

Re: Help with M81 Colors
Just saw this now. Are you using DSS? I think the flats are working if only because when I don't use flats there are some pronounced gradients caused by how the ICX274 is produced and I tried with nebulosity but got a similar result. I have been happy with this camera because it picks up a lot more ...

Re: Running Man Nebula
I usually go 5 min (my sky washes out at 6min to 7min) but I happened to have all the dark files for 3.5 min so I went with that. Keep in mind this is a hyperstar at F2.

Running Man Nebula
So dithering turned out to be very helpful in solving the issues I was having with the pattern noise. However, I'm having some weird gradient issues processing in Startools so I thought I would post to see if anyone had ideas on what could be causing the issue. I tried to increase precision in wipe....

Re: Help with M81 Colors
Because I am a little bit concerned that I'm doing something wrong creating my flats, darks, lights, and bias frames I have zipped the entire package which can be downloaded below.
Thanks for the help!

Re: Help with M81 Colors
Here is the image processed in DSS with 20 darks.

and my best attempt so far (note I don't push the black point too far and I tend to not apply lots of noise reduction)

I'm working on ordering a new camera this week. Probably a Atik 460/490/4120

Re: Help with M81 Colors
I did take flats and bias but I currently have no way to dither and this particular camera (even after being replaced) seems to have strong noise. I have not taken darks yet but I intend to do that tonight. I always use a light pollution filter (IDAS D1). Do you have a stacking program you recommend...
