Lever available to achieve more accurate PA?

Hi,

I have a WD-17 installed at a remote observatory and am using NINA’s Three Point Polar Alignment tool to measure and correct my polar alignment error in real time.

I’ve found that one full rotation of the azimuth knob corresponds to approximately 1 degree of correction, and one full rotation of the altitude knob corresponds to approximately 1.5 degrees. While this is manageable for coarse adjustments, getting the alignment under 1 arcminute of total error requires turning the knobs to within 1/60th to 1/90th of a full rotation — which is extremely difficult to control by feel alone.

For remote observatory use where someone else is physically adjusting the mount while I read live TPPA numbers remotely, this level of precision is very hard to achieve with the standard knobs.

I’d like to ask:

  1. Does WarpAstron offer, or plan to offer, a fine adjustment arm or micrometer adjuster accessory for the WD-17 polar alignment knobs? A lever arm on the knobs would give much finer mechanical control over each small adjustment.

  2. Is there a recommended technique or tool for achieving sub-1-arcminute polar alignment on the WD-17?
