• For an equatorial mount, the alignment star’s declination must be between -75 and +75
degrees.

the altitude limits defined by the user (Section 6.3) .
Not all combinations of alignment stars are good for a 2-star alignment or 3-star alignment.
The SynScan hand control uses a built-in advanced alignment star filter to show only the stars
which is suitable to work with the 1 st or 2 nd alignment star(s), when asking the user to choose
the 2 nd or 3 rd alignment star. It helps to improve the success rate of the alignment.
