Galaxies

M31
M31 (the Andromeda Nebula) is actually a naked eye object under clear skies and can be fairly easily detected with binoculars under most skies.. Through an 8" LX200, the neighbouring galaxies of M32 and M110 can also be seen. The eye is only able to see the brighter nuclei of these galaxies however.

M33 
M33 is a difficult galaxy to view due to its low surface brightness.  I first attempted to view M33 in 1995, but it was not until 1996-Nov-07 that I first located it as a very dim patch of fuzzy light.   I took a photo of M33 in 1999 and later some CCD images in 2003

NGC 7331 - Spiral Galaxy

NGC 7331 in Pegasus, part of Deer Lick Galaxy Cluster.  This was the first deep sky object that I successfully imaged . The fainter galaxy, NGC 7337 is just visible.
