The new unit for attaching to an old tripod. An added item is a ball joint I found in the junk box. That enables me to tilt the camera to film more of the sky if that has interesting cloud formations. Also added is a switch which gives me two different speeds of rotation:
A couple of test videos with the Toshiba at different angles:
Those were videoed at the slower speed of rotation which does look more jerky.
It may be better to use the faster speed and then slow it down in the video editor.
