Comet C / 2019 L3 (Atlas) from 1/2.10.2021. The observation object changed from an exoplanet transit to a comet, because the clouds in the sky varied so much from the early night. Images from a nearly 17-year-old CCD camera are starting to have quite a lot of hot pixels, so the image becomes quite hazy. The darks have been bad too. The negative image shows the size of the comet better. Exposure time was 120 s, R filter, sum image stacked from about 30 images. Image field size about 20 ′ x 15 ′. The comet was in the constellation of Ilves at the time of shooting, ie in the night sky quite low in the east.
