M33 -- the Triangulum Galaxy. This face-on spiral galaxy covers an area about the same size as the moon, and is one of the three spirals in our Local Group of galaxies, along with M31 and our own Milky Way.  This image was taken with a 10" f/10 LX-200 working at f/5 with an ST-7 and is a two-frame mosaic.  Each frame is the sum of two 5-minute exposures.  Processing, besides calibration, was gamma-stretching and mild unsharp-masking.  I used DeepSky to process.  The original is 1024x768 with 1.4 arc-sec^2 / pixel.
