The first pic is of galaxy NGC-3077 that you spotted, Wescott, in your scope at Craters, Friday night. NGC-3077 is an irregular galaxy, at 10.6 magnitude, belonging to the M-81, M-82 group. They are all gravitationally interacting with each other, making one revolution as a group, every 100 million years. NGC 3077 sits about 70 degrees above M-81 at about the same separation as 81 appears to be from 82. All 3 are roughly 12 million LY from earth. The photo was with a Canon 20D set at 3200 iso for 30 seconds. It was at prime focus on a Celestron GPS 11 SCT at f/10.
The second pic is of M-45 Pleiades. It was also with a Canon 20D at 1600 iso and exposed for 5 minutes. The camera was at prime focus on a 6" f/4 newtonian on an EQ mount. The guiding was done visually through a 3" f/7 refractor running at 150X.
