My version of the recent Comet C/2022 E3 (ZTF), whilst zipping through the constellation Auriga a few days ago. Processed from a stack 100 light frames, each with an exposure of 60s. Deep Sky Stacker image processing application used to track the comet across the stack of images, while letting the background stars blur. The ion tail is visible here shooting off to the top left. Star trails are the 'smudges' going from bottom left to top right.

I realise the bloating of the stars is due more to careless processing than major focus issues.
