Next test
Follow up from the test last night. Clouds rolled in an termniated my session but the tracking was much improved.
I did a multiple alignment in the starbook and got +/- DEC behaviour gain. This is a strng indication that the starbook does indeed send DEC corrections during tracking to compensate for poor polar alignment.
My original thinking was to correct this I would have to re-set the starbook and run unaligned but before I did so I adjusted the backlash compensation in the starbook. (I have been advised not to use this in the past).
To my happy surprise the mount proceeded to deal happily with DEC corrections in both senses with no overshoot. I think I have my problem solved....
And yes Fred those axes are in arc secs...
