Offset issue - not sure how to correct
Hi everyone - processing some data with the new PC I built (wow... 31 threads and 64gb ram - process in 1hr data Altair 26c data in 2 mins!) from 2 nights using a Hubble palette (HA, Oii from a triband filter and created Sii channel) resulted in this weird offset. I'm guessing the camera was rotated slightly between nights 🙁 Is there any way to correct this? Thanks!
Mmm, are you using an equatorial mount? It should be registered properly otherwise. I don't have much experience with rotation, but this looks like field rotation somehow.
