Dan, you need focal length, lots of it to make planets larger and clear. Unfortunately, ways of lengthening the focal length of your scope ( like barlows), slow down the optical 'speed' and thus you need increasingly longer exposure time to take a traditional long exposure image. You would also need a very good equatorial mount to track that planet, and you would need to guide that mount.
One popular way around this, is called lucky imaging, where you take a constant stream of video at high frame rate and then use software (like Sharpcap) to stack all those video frames. This can still require a rudimentary mount, but guiding can be avoided because high frame rate video can pile up alot of frames in 60 seconds. But for that to work you need a high frame rate video capable camera. Does your DSLR have video capability?
Suggest you search for info on "lucky imaging" to start with.

Imaging has a big learning curve, but starting with the Moon and a dslr is pretty much where everyone begins.

Certainly for the moon you should have no problems because its so bright, you can shoot short duration shots.
