Hi Joel, Yes this is a very good article, indeed. Also check out Sean's efforts
here - all with a "point and shoot" camera - not a DSLR.
My only advice is: don't jump in too quickly. It is an expensive path to take. Start with the basics and try some afocal photography with yopur DSLR. Get the "feel" for the telescope and understand the relationship between the scope and the camera.
You can buy an adapter to attach the camera body (minus the lens) onto the telescope focuser, called a "T Adapter". Again, see Mike's article under
Prime Focus Imaging Techniques.
You may find you do not have enough travel in the focuser to acheive focus. If this is a problem, then, depending on what brand of Dobsonian you have , there are a couple of options to modify your scope. These are discussed at length an many forums on the internet, including here at IIS. The easiest of the modifications is replacing the focuser with a "low-profile focuser". Having said all that, don't strees about all that yet. Just start trying some Afocal shots, then pick youself up the T Adapter and go from there.
There is plenty of help in this forum if you get stuck.
Stephen
