GP-DX: shaky to focus at high mag, kind of at the limit. HAL110 tripod inadequate.
Sphinx: shaky to focus at high mag, a tad more stable than the GP-DX. Tripod a bit inadequate.
EM-200: still shaky to focus, esp. for high mag planetary webcamming. Acceptable.
A-P Mach 1: Decent with the Eagle metal tripod. Good.
