First light with AT8RC

First night out was a bit awkward, as my first target was cut short by some poor planning on my part. Had I realized before I started that the camera was going to travel right on into the tripod in just 100 or so frames, I would have just taken all the pictures on the other target. Honest, I wasn't drinking. Guess I was just a tad bit excited.

As such, 100 or so frames were certainly not enough to produce good results, but 200+ frames were just fine for a reshoot of the Pinwheel Galaxy, Messier 33 (M33).

Roughly half the diameter of our own Milky Way galaxy, M33 is a mere 3 million light years distant. Certainly nothing like "Five Million Years to Earth." This shoot was unguided, with 237 x 15 sec. JPEG frames, using a modified Canon 450D DSLR. Calibrated, stacked, DDP and unsharp mask applied using Nebulosity.

I love the improved magnification at prime focus with this scope...encourages me to go after some of the more smaller galaxies that I used to have second thoughts about.

Guess it is a bit reddish though. Should work on my color balance.
