Title

3 x 2 degree Field - Closeup - C/2022 E3 (ZTF) 2023-01-28 Although I took over 700 sub frames of 15 seconds each, this image is only a stack of 40. That's only 10 minutes!!! That's why it is so messy. The comet was moving over 19,000"/day. I perhaps will stack all the images one day...anyone interested in some data? Storms a commin.
