Binocular comet Iwamoto - 4.3.2019 at 00.00 - 4.3.2019 at 00.30 Kolari, Äkäslompolo Observation number 81564

Visibility V / V

Lauri Turunen, Corona Borealis, Rovaniemi

You can also take astrophotos on a ski holiday! I set up the camera in the yard of the rental cottage and aimed a 200-millimeter lens towards the Driver's constellation. The comet Iwamoto cools down in space so fast (230,000 km / h relative to the ground) that I stacked just over 20 minutes of exposure in the image below. The picture also shows nicely e.g. Flaming Star Nebula and the open constellations Messier 36 and 38.

On kyllä todella tyylikäs kenttä tuolla polttovälillä!

Alkuperäisestä kuvasta piti rajata lähes kolmannes pois, kun flat-kuvilla ja kuvankäsittelyllä en saanut kunnolla poistettua vinjetointia. Ilmeisesti katulampuista tuli sen verran hajavaloa.
