Used 30 minutes of 30-second exposures to star align and stack, produce a starfield, then comet align and stack with the starfield subtracted.

After finally figuring out how to process comet, I felt C/2022 E3 (ZTF) in particular would look nice without stars. It has a laser-like tail, dull red anti-tail and distinct green core. You can watch a live image of the comet through my telescope in the timelapse I created here: https://youtu.be/U_eFbxtzWNc
