Guiding help

[Alan Moore]

I have a telescope at Starfront observatories and have been very pleased with their equipment setup and customer service.   However tonight was the first clear night in a couple of weeks and I'm having trouble with guiding.   My Ha exposures were 300 seconds and there is definite north drift.   I've run the calibration assistant and the guiding assistant several times.   My 300 second exposures show significant star trailing.   The guiding graph show a consistent drift and then loses the guide star, then resets.   As long as I stay under 120 seconds the subs are decent.   I've tired a variety of exposure times as shown in the attached guiding log without any difference.   My frustration is that I can't check the rig as its several hundred miles away.   I'm hoping you can find a problem that I can send to them to correct this.

Thank you
