M44 - 15.3.2018 at 00.00 - 15.3.2018 at 00.00 Kiiminki Observation number 73432

Visibility IV / V

Arto Murtovaara, Oulun Arktos

I photographed this great open set in February-March, the 6 "Newton I made gives the reducer a field of view of about a couple of degrees and this object also easily fit in the field. The M44 was the last subject photographed with this tube this season. 342925 /? Nc = user
