Antique Restorer

Hi guys, Being on a tight budget I have just bought a 40D to use for starting out in Astro photography, and was horrified when reading a different forum that there were a lot of negative comments about the 40D for this use, I was wondering if I had bought a bit of a "pup", however your comments here have reassured me somewhat, thanks, I am now thinking that perhaps they were just "gear snobs" as I have to admit the 40D is starting to show it's age, I am as I said only starting out so the whole removal of components thing is a little way off yet for me, but thanks for not being negative about the camera...lol
