Atik 420 picture size?

[Ressler]

Hello everyone,,
Ok getting the hang of the 420. Using it with the Hyperstar and my Celestron Edge HD8 scope. So far so good. Although I am very surprised that the fits files I am getting are so small in size. Generally 1-2 mb Which is giving me some problems when I go to post processing. Even stacked. I am trying to use the Atik software as much as I can. Is there some setting where can change this? I dont understand why they would be so small in size. Suggestions? Ideas?

Hello,

The file size should be close to the double the amount of pixels so in this case just under 4mb. If it's closer to 1mp do you have binning 2x2 selected? Or do you have a ROI selected?
