I have heard of this done before! From what I remember from a couple of years ago the people that did this used a small circular camera/device in a holder which was mounted on top of the telescope. The camera/device was then connected up to a laptop which was used to capture the image of what the people was looking at through the telescope. I am not sure how the camera communicated with the laptop whether it was via cable or by wireless.
Re: [SERIOUS]Exposure Time
You're seriously wasting your time. Use mathematics. All basic data can be retrieved from existing catalogs.
Re: [SERIOUS]Exposure Time
I'm in agreement with Max on this.
But in any case an exposure of 10 seconds will give you all the Naked-Eye Visible stars and also a few of the brighter non-NEV ones. Much longer than that and you'll end up with lots of unsightly noise in the images.

I'll take Max's plan into consideration. I'll struggle a bit with the maths (judged from the link he included in his post) but I'll give it a shot in any case.
As for the exposure time, I actually found this page. Very informative.
