Binocular comet ZTF - 31.1.2023 at 19.00 Kurikka Observation number 111811

Visibility II / V

Marko Myllyniemi, Lakeuden Ursa

Despite the bright moon in the sky, I decided to try photographing ZTF with camera optics. After a few "search photos", the comet was also found in the photos and was moderately visible despite the light night sky. The focus had (once again) unfortunately slipped towards the forest...

I took exposures at 20 second, 15 second and 10 second exposures which I combined with the Sequator. In total, 11 minutes and 40 seconds of exposure were accumulated (although an unacceptably few of those were torn off despite the exposure).

At the time, there was a satellite congestion in that direction, I made the streaks disappear from the triple image when I set the stacking setting to "select best pixels" in Sequator. In the last picture, a black and white negative.

Maybe a bit of a tail could be seen when you didn't try to adjust the sky too dark.
