Imaged Comet C/2022 E3 (ZTF) on the night of February 3, 2023. This was my fourth imaging session with this incredible comet, but the first with the moon interfering. The green coma and dust tail are still nicely visible, but the ion tail is just barely visible now due to light pollution and moonlight.
Imaged with Astrotech AT60 at F/4.8 (288 mm focal length) using Astrotech ATRF60 field flattener/0.8x reducer, UVIRcut filter, and full spectrum modified Nikon D5300. Total integration time of 25 minutes from 25 subs at ISO200 x 60 sec.
Pre-processed using Pixinsight's weighted batch pre-processing script (WBPP) to perform calibration, debayering, registration.
