Polar alignment assist
This function tells you the amount and direction you need to turn the mount's altitude
find adjustment knob and azimuth find adjustment knob for polar alignment. This is an
auxiliary function to use when you do not have an electronic polar telescope or polar
alignment software, or when the Polaris is not visible. This function may not be accurate
as it is affected by the precision of star alignment and the mechanical play of the fine
adjustment knob.
After aligning 3 or more stars, this function is activated. (5 star alignment is
recommended.) Among products shipped before April 2020, the amount of rotation of
the fine adjustment knob is not correct for products that have not upgraded the polar
axis adjustment part. In this case, please rotate about half the amount of rotation
indicated on the screen.
