It is not a full frame sensor. It's a cropped sensor which gives 1.6x magnification. Canon has the 5D and 1Ds for Full Frame 35mm like framing.
So every lens you get, you will have to multiply the focal length numbers by 1.6x to get the actually range you'll be getting.
It's nothing bad, but just reminding you so you can do calculations correct on time you can go without star trails.
Also, how did you go 30 seconds at 300mm with no tracking?
