Hi Rob...
While it is possible to take planetary shots with a DSLR...it's really not the 'weapon of choice'.
Others will chime in here with what settings are best when taking a single shot of planets with a DSLR, but I'll suggest you lay your hands on something like a ToUcam (webcam) hooked up to a laptop and combined with your telescope to capture small videos called AVIs.
You can then take the single frames from this movie and stack them in free software to produce a single image which can then be further worked on in your photo editing software of choice.
