Astrophotography - 2nd Try at Mars

Just another set using the 40D with a 400mm and two 1.4x teleconverters. The first moon shot was taken on the afternoon of a particularly clear and cool day. The photo of the dot is Mars and is my second attempt. I didn't blow out (overexpose) the disk of Mars, but it's still a little too fuzzy to make out much detail other than its slightly reddish hue (it's a 100% crop).
