I must be the Dummy that PHD was written for but it's still giving problems.

The guide Camera setup is an un-moded Phillips Toucam fitted to a 35mm camera lens adapter I made so I could fit any focal length lens I liked.
The lens in the picture is a 135mm f/2.8 and I have also tried a 77mm f/1.8 and a 50mm f/1.7

The main problem is RA calibration keeps failing due to the star not moving enough error.
I did get it to cal once after making some Azimuth corrections to the mount to help with DEC drift but that was short lived as when I moved to a new area of sky and tried to recalibrate, same old problem.

How far does the star have to move to get the calibration to pass and can you force this, also the numbers displayed at the bottom of the PHD window during calibration, what significance have they to the cal.

The Laptop connection is via a GPUSB and is functioning ok as I can select manual drive and that works ok.

Any help grateful.

Nico.
