Binocular comet ATLAS - 4.4.2020 at 21.53 - 4.4.2020 at 22.56 Hyvinkää Observation number 89675

Visibility III / V

Timo Inkinen, Ursa (Etelä-Suomi)

Comet C / 2019 Y4 Atlas, filmed on Saturday night, April 4, 2020, had not changed much in my observation on April 1, 2020. A bit of a tail start and a comma that easily catches on photos still with that kind of total exposure in less than an hour.

This comet gradually drifts more and more behind the yard trees, so when I shoot through a telescope, I guess I leave the job to this. This time I used to shoot only 47x75s partial exposures with a TMB 152/1200 lens tube and an ASI 183MM Pro camera before the tree tops came to the front.
