M33 The Pinwheel galaxy

I took this pic on the same night as M45 (below). With a great deal of humidity in the air. This was taken before M45 and is just a small stack of 35 x 1 minute exposures at Iso 800 Unguided. It was really just a test of focus and balance really so I wasn't serious about this set. As the night previous I had run a sequence on M37 and M38, having taken a couple of hours worth of photons on processing to find focus was out by probably one tenth of a mm "gutted" Me thinks an electronic focuser is on my christmas list?


With a diameter of about 50,000 light years, the Triangulum galaxy is the third largest member of the Local Group, a group of galaxies which also contains the Milky Way Galaxy and the Andromeda Galaxy, and it may be a gravitationally bound companion of the Andromeda Galaxy. Triangulum may be home to 40 billion stars, compared to 400 billion for the Milky Way, and 1000 billion stars for Andromeda.
