GP-C5 mount

I am wondering if there is any concise instructions online for using the
setting circles
on the GP or C5 mount? After polar aligning, what is done next to set up
the setting circles?

Hi Mick,

Just choose a bright star with known coordinates to point the scope at, and
turn the Right Ascension setting circle to match the RA coordinate of the
star. Use a star close to the Celestial Equator (at a right angle to the
pole) for the most accurate alignment.

The declination setting circle should already be aligned. If it’s not, use
the same star as in the previous step and set its declination as accurately
as possible on the declination scale.

Of course you should then lock the setting circles to follow the movement of
the RA and dec axes.

Here is a list of some bright stars useful for aligning the setting circles:
