I’m used to doing equatorial-mounted astrophotography in the past, but I got rid of a lot of my gear so I’ve been stuck with a defective alt-az LX90 for all of the recent astro opportunities. I have been trying to learn how to post-process on some of the recent stuff I’ve shot - practicing on the moon, along with the Jupiter / Saturn conjunction. I use Mac, so I’ve tried most of what’s out there for it and it seems that Siril is one of the better apps that has kept up with the recent OS upgrades and security changes.
Longer sequences of the moon (>a minute or two) have field rotation due to the alt-az scope mounting and aren’t being registered correctly. They spin around the center. I’m using the “Enhanced Correlation Coefficient” mode. I’ve tried the other planetary option - “Image Pattern Alignment”, but it only looks at the reference image and then stops.
What am I doing wrong?
