Ok, I have now a R, G, B, Ha, OIII and SII stack, all registered to one master, but they do differ in size because they are all taken on different days (in 2016 and 2017) and with two different camera’s which were mounted using a different rotation.
What is the procedure in APP to make them all similar without loosing the alignment, (so without shifting them on the X and Y axles).
Can this also be done in APP as well so I have done the complete processing using only this application?
Once this is done I can do the Combine RGB option in the 9) TOOLS tab to transfer to color and do the final tweaks…
