This is a couple really long exposures showing the astronomers (and the stars) in action.
|one 15 min exposure|
|and 30 min|
Then I strapped my camera to the big scope and pointed it at a spectacular pair located in Ursa Major. M81 and M82 also known as Bode's Galaxy and Cigar Galaxy are quite a dynamic duo. M81 is a very large face on spiral galaxy and M82 is a unique starburst galaxy that is churning out stars on a massive scale being helped along by tidal forces from it's large neighbor M81. There's a small galaxy on the lower left called NGC 3077, it's is also an irregular galaxy likely being acted upon by it's larger neighbor as well.
