Camera About this Image mag 5 sky, good transparency, temperature 2 C 16 cassegrain in primefocus at f/3 Astronomik LRGB H alpha M81 and M82 Galaxies Optics Technical Details LRGB = 60303030 minutes (10 minute sub exposures), 60 min Halpha (30 minute sub exposures) at f/3; combined with seperate exposures at f/10
Jan 14, 2005 for f/3 Jan Feb 2006 for f/10. Date Sky Conditions Filters MK 100 GEM Mount The two famous galaxies M 81 (left) and M 82 (right) in Ursa Major are situated 12 million light years away. M 81 Bodes face on galaxy shows tidal interaction from the only 150000 light years distant M 82, the Cigar galaxy is distorted by the gravitational interaction with M 81 and shows strong H alpha streamers in direction of the rotation axis far out from the galactic plane. The f/3 data have been reworked with data at f/10 for M 81 and M 82, find the higher resolution images and more information here M 81 and M 82
