Comet C/2022 E3 (ZTF) in Auriga
This image is the result of 63 minutes of LRGB data capture on 7th February 2023, with 30sec exposures. At the time, the comet was 33 million miles from Earth and 110 million miles from the Sun, so between the orbits of Earth and Mars. At magnitude 6.2, it was just below naked eye visibility, half a magnitude dimmer than at its peak a week earlier.
The image was stacked on the comet, so the stars are trailed. They take the form of a series of LRGB dots, with 10-second gaps for filter changes.
A ZWO ASI2600MM Pro camera was used, through an 8-inch Teleskop-Service Ritchey-Chretien reflector, from Horsham.
