greetings, I shot some raw frames with the 60Da and stacked them in DSS 3.3.2. They are full frame images with a wide field through a FS60 scope. This is the first time I have tried to stack 60Da images with DSS. I thought I had changed settings back after stacking QHY 8 OSC camera stacks in DSS, but the resulting stacked image is a thin rectangle in the middle of the DSS screen. This has never happened to me before and I don't know why. I can't work out what went wrong.
Help please
Graham
