Hi Kevin, getting all experimental eh ? A good sign around here..
Welcome
Probably just easier to buy a proper webcam with it's associated drivers etc. The laptop webcams are small and not big on resolution and the lens and short focal length are marginal at best. Drivers will be specific for the laptop mostly with limited control for gain and exposure. Physically not easy to play with either.
They are getting a bit old now but the Phillips SPC900 was heavily used before by experimenters as it was relatively easy to modify and had a decent sensor. Others have attacked the MS Lifecams.
If you just want to try a webcam out any cheapo unit that can be physically hacked around and fitted to a scope is usable and there is free software like SharpCap or Am Cam and others that will let you do moon video and stacking. Moon is a good place to start, big bright and some detail to be resolved. You don't even have to track too accurately, movement is expected.
I did daylight tests first to find focus and some settings. My First 'webcam' was just the board from one hacked into a plastic film can which just happens to be the right size for the focusser EP hole.
Now go and play with it all, if you try the laptop cam let us know how it goes.
EDIT: Magnification will be set by the focal length of the scope, chuck the laptop lens away. Prime focus is the story.
