Tim,
Welcome to IIS.

I'd suggest finding your nearest Astro Society and joining them on an open night. You'll see first hand what is involved in Astro Imaging.
As Niko said, most of us started on this slippery slope by butting our camera lenses up to the eyepiece and snapping some shots of the Moon. If that whets your appetite for more, well, I hope you love a challenge because the learning curve is steep and the gear can be quite expensive. Personally I love it.

For all the nights of frustration and tearing your hair out trying to get hardware and software working harmoniously together, that first night when everything just works and you end up with a gorgeous image that is YOURS, that you took, it's so worth it.
