Re: leveling the RAPAS on Mach2


My thinking has been that if the RAPAS is properly calibrated to the Mach2's RA axis, then a non-leveled tripod won't make a difference. Once the polar axis is precisely aligned, it does not care what is going on below. In the past, the difficulty from a non-level mount presents itself when trying to drift align. Adjustments in alt and az are intertwined. You'd really need a level tripod to calibrate the RAPAS, but perhaps once that is done, you should be fine.

But I may be mistaken in this notion as I don't fully understand how the absolute encoders work. Perhaps an azimuth tilt in an otherwise precisely aligned polar axis would affect how the Mach2 perceives its position. Would the ultra precise Home Position then be off?
