Description

The Bode Galaxy is a spiral galaxy located about 12 million light-years from Earth in the northern constellation Ursa Major. M81 is estimated to contain about 250 billion stars, making it slightly smaller than our Milky Way. It and the nearby irregular galaxy M82 are the most prominent members of the M81 galaxy group, of which M81 itself is the principal member; it seems that the two galaxies met a few million years ago, causing the deformation of M82. Technical data: 204*180s G1600 T-20 34*120s G1600 T-20 79*900s G1600 T-20 Equipment:Skywatcher 254 F5 @1033mm (F4) Skywatcher 0.87x Coma Corrector QHYCCD QHY294c L-ProOptolong  L-Ultimate ZWO OAG + ASI290mm Mini Ioptron CEM70 Software: NINA+PHD2 Shots by my friend Francesco Radici Dome processing by me
