I took this last night with an ap 1200 mount.
I took an ok 60 second guided shot and then tried guiding, focal length
1600mm. I used .5 guiding and calibrated at .5x. When I did the
star stayed on the little autoguiding chip the whole exposure. I did not
play with backlash at all. I used a bunch of different settings on maxim
guiding, but didn't try to change backlash in guider settings.
I even tried the Roland calibrate at 1x and guide
at .5x trick and got the same results.
I think it is dec backlash, can anyone help?
The ap mount manual says to depress one dip switch at a time till backlash
gone. I was too tuckered out to mess with it.
