Comet Stacking / by Jeff Tropeano

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.

Comet C/2014 Q2 Lovejoy moving against background stars over 60 minutes.

Guess I'll have to run it again.

Harry from has a good video tutorial on processing a comet in PixInsight.  I'll be using his guide this time!
