Jupiter & Saturn filmed with a Skywatcher 150PL & a HP-4110 Webcam first attempt, the webcam is full HD and has been modified to fit with a 1.25" focuser. i did not use any barlow lens the webcam just pointed at the secondary mirror.

Ed ~ For a CMOS sensor this is very good. Unsure on how simple it is to attach it to a telescope, but seems to be a case of just removing the lens.  And it seems to do the job.  But i probably wouldn't recommend that you buy a new one for astrophotography.
