Has anyone captured Jupitor or Saturn through this? Has anyone tried it attached through a large Dob?

This camera is a severely over priced web cam.

If I recall correctly, the native 5mm equivalent focal length means that even with a 0.5X Antares focal reducer on the camera, the sky flies through the image; tracking is essential to even get the image into the FOV. I was using it on an 18" f/5 Teeter dob with no tracking. Maybe with a lot of practice one could develop the human powered skill to keep the object centered, but life is too short for me to work at it. I reverted to the 10" SCT.

Any alternate thoughts on an economical means ($100)of capturing images through the focuser of a Dob for planetary viewing? I was thinking of using a 2x Powermate instead of focal reducer. At 10 to 15 shots per second, can't you capture the planetary image rather quickly (instantaneously).

Does using a Flip mirror diagonal help with the manual focusing and keeping image in sight prior to focusing on computer?

I should clarify. My comments were related to using the SSSSI IV one night on the big 18" f/5. I have acquaintances who in fact use web cams to take image bursts with 8" f/6 and 10" f/4.8 dobs and post process the image stack. I just couldn't believe how fast the image field blew across the monitor screen so I gave up immediately. Dob and web cam use on planets is often done. I just had no patience to try, with the small, high power field of view of the Orion device.

I completely understand and its part of the paradox of trying with the SSSCI IV or NexImage 5 in a Dob. They are both relatively cheap and obviously not made for the problems associated with Dobs and accuracy in tracking.
