Thanks Mark, glad you liked them. With the Rebel I found that ISO 800 gives the best S/N. I was imaging from our clubs observatory. I ended up loosing 7 subs on the Sombrero when I went to the warm room for a coffee and the guider ran out of sky. It was still tracking but the stars were not nice and round. It would have been nice to have the extra half hr or so of data.
