Hy,

Thanks for all your work on this. I tried to switch back to the internal guider from PHD2 the other night, but was halted by DEC backlash issues during calibration. I took my scope down and have chased this to tune it up a bit, but I also wonder whether there shouldn't be an option to disable reverse DEC moves during calibration. This still allows the calibration angles to be set, but avoids getting stuck by DEC backlash. Forward calibrations would work normally, and reverse motion on RA would still function the same. Not doing a DEC offset back to original position would force the user to resolve (if desired), but that seems minor. This could open more doors for folks with DEC backlash.

Now that I think of it, I'm not sure there's an equivalent option as in PHD2 to set or disable the DEC guide direction. Do we have that? That feature would be desired too (so some folks could intentionally misalign PA, forcing DEC motions to be unidirectional. Anyway, just a couple of thoughts to possibly make this handle some bad cases slightly better.

Cheers, Doug
