2.3Pointing the telescope with the EQM-35 mount
A problem for many beginners is recognizing that a polar-aligned, equatorial mount acts
like an alt-azimuth mount where the RA axis has been aligned to a celestial pole.
Once aligned,the RA axis allows rotation as shown in fig 17 where it scans the “new
horizon”.
That scanning movement is the Right Ascension (RA) movement.
Part of the new horizon is usually blocked by the Earth.
This “new horizon” is called Plane of Celestial Equator.
The other movement of the mount, square to this first movement, is the DEClination
movement.
