The manual has the following tip:
It doesn’t make any difference where the magnetic switch is located on the dome, but it is recommended to place the dome magnet on the south side of the dome when it is in parked position for domes installed in northern hemisphere, and placed on north side on domes in southern hemisphere
I put mine where the shutter charger was figuring this just being a very simple offset I configure in software somewhere ( still holding that expectation ) to capture the relative offset of the shutter to true north. However given both gear slippage problems and prism/poth/device hub - I haven't figure out exactly what I'm doing here. Should I put the magnetic sensor in some other position to make shutter alignment to telescope azimuth easy? I still haven't achieved software control aligning to aligned scope azimuth...
Also, I have my gear system installed to the east side of the dome, when I press the buttons I get the opposite direction of rotation I'd expect. But then I noticed prism's software display rotating the opposite direction the dome rotated in as well. Is there a sign flip I can have applied in the nexdome software control somewhere...?
