Imaged Comet C/2022 E3 (ZTF) on the evening of January 30, 2023. This was a great night for imaging with the comet nicely placed in the evening sky and the conjunction of Mars and the Moon.
Imaged with a William Optics GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, UVIRcut filter, and ZWO ASI 533MC Pro. Total integration time of 20 minutes: 20 subs at Gain = 100 with an exposure time of 60 sec.
Pre-processed using Pixinsight's weighted batch pre-processing script (WBPP) to perform calibration, debayering, registration.
