Binocular comet ZTF - 26.1.2023 at 21.32 Kurikka Observation number 111592

Visibility I / V

Marko Myllyniemi, Lakeuden Ursa

I looked the other day that comet C/2022 E3 (ZTF) could be easily found in the vicinity of Little Bear's bucket, so I had to try it out with camera optics. Since I was using a telephoto zoom lens, I locked the focal length with masking tape (to prevent the tube from spilling) at 135mm. The focus seems to be a bit on the soft side...

I snapped 22 20-second exposures of the subject, which I stacked with the Sequator. The first image without Sequator light pollution filtering and the second with it. Third image stacked with Deep Sky Stacker. Post-processing of all images in Photoshop.

Maybe a little more exposure would have been needed... :-/
