The various Astrophotography books I have all suggest a web cam generally outperforms a DSLR for astro photography (using video mode & image stacking the resultant frames - Deep sky stacker is one of the recomended software packages IIRC).
More modern DSLRs with movie modes might have changed this.

My own attempts have been disapointing, mounting my camera onto a zoom eyepiece, with a 6" reflector. I managed to get photos of Jupiters Galilean moons, but the overexposed image of Jupiter itself (in particular) show what I think must be Chromatic aberation from the eyepiece.

I've since got several other options for connecting my camera. I seem to remmember the prime focus approach didn't work as the telescopes focus control had too little movement.

Unfortunatly my Parents moved last year so I no longer have access to the fairly dark skies around their house. Perhaps I'll find somewhere local to play with it all again (and the time/energy...)
