Hallo,

i want to stack RGB frames with Halpha and OIII frames.

After cropping the RGB  ,Halpha and OIII frames they have different dimensions (for example 4023*2021 and 4142*2011)

Stacking is not possible. Is there a way to get the same dimension?

best regards

Rainer

Yes, by aligning them all together. You do this by splitting the RGB up into separate channels, to make them mono (tab 2, split channels option). And then to reload all those mono images in and process accordingly. After that you can combine them into 1 image and then crop. Would that work for you?
