Bumping this as its a perfect place to ask;
I checked out the two flats i took (0sec and 1sec).
After doing some reading i found that the area to aim for in terms of ADU is 30,000 for a DSLR.
My 0 second shots are ~8000 ADU and the 1 second are ~54000.
I didn't need to stretch my 0 second shots to see dust marks, so it looks like it has helped but i guess with the ADU being so low, it didn't get all of it. The shot does have a wave affect on it though, which might be the reason why it doesn't really do anything to my images? (see 1st image). Is this wavy affect normal?
The 1 second shots are just a sheet of grey un-streteched.
I stretched my 1 second shots and got a color pattern. No idea what it means, but im guessing it cant be good (see 2nd image).
-edit-
How strange. The 2nd image as FITS format comes out looking like a pattern my mother would use in sewing. In jpg form its a sheet of grey.
Next time ill try for ~30,000 ADU and see how that goes.
