Tweefo, thanks for posting! I like your first attempt - more in it is recognizable as Saturn than most people would ever see for themselves.
If you live in a built up area with light pollution issues, you will be limited to photographing bright objects like star clusters, planets and the moon. Planets can be awkward due to the high magnification requirements to see any detail, and they are easily over exposed at low magnification. Some people have success by removing the webcam lens so that the telescope objective and the webcam sensor are the only components in the light-train (except for the secondary mirror in newts and cats). Such a sensor gives a magnification (power) about equivalent to a 4-6mm eyepiece. A common way of photographing planets is to take a video stream of the planet (using the same webcam sensor hooked up to your telescope), and then overlay all the hundreds of pictures using a program such as Registax (availble as a free download when I last checked). Its just amazing the amount of detail that can be teased out in this way.
For galaxies and nebulae you will need to drive to a dark location and use long exposures. You will also need an equatorial mount for your telescope, or a wedge, so that the telescope will follow the object, and also turn with the sky.
It’s probably best to start with your camera and a tripod only, and play around with photographing wide swathes of sky. A lot of people get started by making star trails.
ETA, OK, so now I couldn’t resist having a bash at Saturn myself this evening! Its a tricky subject and detail eluded me, but here is what I got, nevertheless. (And admittedly tarted up a bit with a photo editor. :D)
