M106, Spiral Galaxy in Ursa Major

B33, The Horsehead Nebula in Orion
A second clear night in a row gave me a shot at getting a full 2 hours of B33. The sky background sure isn’t dark. The moon was a little bright tonight, […]

NGC 2244, The Rosette Nebula in Monoceros
Finally, a halfway-decent shot of The Rosette Nebula. This object could have been shoehorned into the FOV a little better, and of course would have been a snap in Pumpkin. But Veronica […]
