Were you holding it by hand, Henry??. That's probably the biggest problem you'll have. Unless you have rock steady (and I mean
rock steady) hands, your images will look like a dog's breakfast. To make things a lot easier, and to allow you to get the image into focus all the time, grab yourself one of these....

Just click on the link above and goto page 4. That little device will make things so much easier for you. Then all you have to do is keep the scope pointing at your object
Also, you'll have to set your camera up to take the piccies. For planets, especially bright ones like Jupiter, it's best to take lots of short exposures (1/20th to 1/50th sec) and then stack the piccies with a program like Registax or DSS (Deep Sky Stacker). The Moon only needs very short exposure times....1/200 to 1/1000th sec because it's so bright. You could also drop the ISO down a bit too...ISO200 would be fine, but for other objects ISO400-800 is more recommended.
Your camera is more than sensitive enough....you just need the right equipment and a bit of help. You'll soon be churning out the piccies
