I realize I'm abusing this forum, since this is my third post just today, but I am new at this and being here has helped tremendously in fixing issues and learning new and better ways of doing things. I'm eternally grateful to all who have helped!
So, here's my question - Why won't my bias frames calibrate in Deep Sky Stacker? I've tried everything. I know my bias frames and master are correct. I even created new frames over the weekend. I covered the camera, set the temp to -15 which is where I am always shooting (and I know setting the temp isn't necessary) and I set the gain at the same gain as my lights. Then, I shoot at the fastest possible exposure. When I bring them into DSS it ALWAYS creates a posterized image, like the one below. I want to add bias frames, but have been unable to do so. Any suggestions or ideas would be greatly appreciated.
