If I only am using light frames, do I skip calibration or is there a way I should still use it?
@msamazing You can always skip Calibration and all other steps. Simply load your data in tab 1, go straight to step 6 and click the integrate button. APP will do all intermediate steps by itself.
@wvreeven Thank you very much! One other question. I ended up with the frames being uneven. Do you know what I did wrong to cause this? Please see Attached photo.
@msamazing APP performs a registration of the lights based on the stars it detects in those lights. If necessary APP rotates and scales the lights so they match. It looks like you had at least two imaging sessions and the camera has rotated in between those sessions. If you remove the camera from the scope and put it back on to continue imaging on the same object, you need to make sure that the orientation of the camera matches what it was before.

That’s a tracking issue. The camera didn’t move to keep the frame the same. How did you have the camera mounted?

I'm going to disagree there given the stars look round and also my assumption on length of exposure. I'm agreeing with Wouter, looks like framing etc.
@scotty38 Well, to be fair. @turtlecat1000 wrote tracking issue, not poor guiding. With a sub-optimal polar alignment the frame will rotate over the course of a night and stars can still look round and sharp in the individual frames. Though I would expect not a big jump like in the picture uploaded by @msamazing but rather a smooth distribution of angles. That is why I suspected two separate sessions. But only @msamazing can tell us what happened.

Well yes good points 🙂
