Binocular comet ATLAS - 30.3.2020 at 21.50 - 30.3.2020 at 23.25 Hyvinkää Observation number 89506

Visibility IV / V

Timo Inkinen, Ursa (Etelä-Suomi)

Comet of C / 2019 Y4 (Atlas) filmed on the evening of March 30. The courtyard birches in your yard start to block the telescope views just in the direction of the comet as the evening gets dark. This stack has 57x90s of front exposures that I started shooting just over half an hour before full astronomical darkness came. In the future, I can shoot maybe less than half an hour or less before that Atlas moves after dark to get behind those yard trees in the second picture. You can’t always win in these patterns with a fixed observation shield in your own yard.

EDIT: I added a crop from that stack that shows a comet with dim streaked stars before merging it into the star field. It shows the comet's tail better ...

Technical information

TMB 152/1200 APO lens tube and ZWO ASI 183MM Pro camera, 57x90s partial exposures and tracked by stars + comet connected to the starry sky in PixInsight. The stars require a reasonably more image processing in that, when some of those images seem to have been photographed through a branch of a yard birch.

Eikös tuossa olisi kirveellä töitä ?

Koivusta saa hyvää polttopuuta, jos on tarvetta nimittäin.

Asioilla on puolensa, sillä tuonne koivujen väliin voi ripustaa kesähelteillä riippumaton, jossa voi viettää suhteellisen vilpoisassa olotilassa lomapäivää, kun aukean puolella vallitsee yli +30C hikinen helle ;-) Ja vastapainona tuolle luoteissuunnan peitteisyydelle on pihan puolella 180 asteen vapaa näkyvyys pääsuuntana kaakkoistaivas. En siis ole tarttumassa moottorisahaan tai kirveeseen, vaikka tuo haittaakin komeetta Atlaksen näkymistä.
