This is M31, the great galaxy in Andromeda. It was my first CCD image, taken with a CB245 camera cooled to -25c through an 80mm f/5 Orion short-tube refractor. It's a single 5 minute exposure, dark-frame subtracted and gamma corrected, converted from the original FITS format to JPEG. Best if your display is true color (24 bit) or at least hi color (16 bit).

Left to right:
M51, the Ring Nebula. The central star is easily visible. 10" LX200, 60 seconds(!).

M27, the Dumbell Nebula, 5 stacked 4 minute exposures, 80mm f/5.

M42, the Great Nebula in Orion, 1 minute, 80mm f/5.

The Horsehead nebula in Orion. 4 minutes, 80mm f/5. This isn't visible to the eye at all in my 10" scope!

Left to right:
M51, a really nice example of a sprial galaxy. This is a single, unguided, 4 minute exposure taken through the 10" LX200, processed using maximum entropy deconvolution.

M81, taken through the 80mm refractor. It's a single 4 minute exposure.

M101 from 8 stacked 3 minute exposures through thin clouds. 80mm f/5.

NGC4565, 4 minute, 80mm. If you look closely, you can see the dust lane that bisects this edge-on spiral.

Left to right:
M3, a nice globular cluster. 4 stacked 4 minute exposures, 80mm f/5.

M13, perhaps the best globular in the Northern sky. 2 minutes, 10" LX200

Here's my observatory, with a swing-open roof, and my 10" LX200 with the Orion 80mm short-focus piggybacked on it. You can also (sort of) see the CB245 camera.
