Hello all,
Here's an image I did last weekend of the great southern galaxy NGC 253.
I used the modified Canon 300D on my GSO 12" f/5 telescope,
hand guided with a 4.5-inch f/18 guidescope. I also used a Baader 2" Multi-Purpose Coma Corrector (MPCC), Baader 2" UV/IR Cut Filter, and DSLR focus.
The exposure is a composition of
15 x 3-minute exposures @ ISO 400 - that's 45-minutes total exposure time calibrated with 5 dark images and 5 bias images in Iris.
You can see a higher resolution image at

Note the Asteroid, 2002 VC6, moving through the field at a rather faint 18th magnitude, just to the lower-right of the galaxy core.
