I have a Orion Skyview mount with the goto upgrade. I am trying to use PHD2/EQMOD/APT to auto guide for deep sky astrophotography.
My configuration is using the EQDir cable from my USB hub to the mount controller box so I dont need the hand controller.
Everything "works" but the auto guiding accuracy is terrible. Sometimes the calibration fails. When it gets through calibration, the RA and Dec commands are all over the place with RMS of 0.88 and 1.19 respectively. Peak of 2.19" and 3.44"! Calibration fails with a error about unable to eliminate Dec backlash or something.
I was unable to take any subs longer than 20 seconds or else I would see oblong stars!
Has anybody got auto guiding to work with the Orion skyview Pro goto mount?
If so, what PHD2 settings did you use?
Should I upgrade my mount? (like to a HEQ5/6)
