Cheers P&C
Can someone help me out here.
As we know with a SCT when you adjust focus the primary mirror is moving which results in a small change in focal length. I notice in my FC logs that 1 batch of data would be at FL4000, another at FL4150 and also FL4100.
When de-rotating a stack of images in WinJUPOS, does the stack of images need to be the same focal lengths and sequence?
