Telescopic comet Smirnova-Chernykh - 11.3.2017 at 22.18 - 11.3.2017 at 22.37 Orimattila, Artjärvi, Tähtikallio Observation number 62011

Visibility I / V

74P / Smirnova – Chernykh
Comet as a training object during the Tähtikallio photometry workshop. Alluna's Shooting Team:
Ville Miettinen, Veikko Mäkelä, Jorma Ryske, Timo Kantola, Janne Voutilainen, Tapio Lahtinen and the undersigned.
Images calibrated with MuniWin, stacked and comet photometrically measured brightness mag 18.1 MaxinmDL v.4.5. The target was so dotted, without the tail that some sort of measurement was successful. Calibration was better for MuniWin than MaximDL, so I used it.
