I shot my first comet last night from the backyard: Comet C/2014 Q2 Lovejoy.
After my capturing session, I set PixInsight to pre-process the images, but forgot one very important thing about comets. They move. You can see the streak of movement in the comet against the background star field. This is almost 60 minutes of imaging.
Guess I'll have to run it again.
Harry from harrysastroshed.com has a good video tutorial on processing a comet in PixInsight. I'll be using his guide this time!
