Pointing accuracy
Pointing accuracy depends on a number of
factors:
• Quality of the telescope mount
• Choice of alignment stars
• Accuracy in pointing on alignment objects
To achieve the best pointing accuracy with an
Altitude-Azimuth mount it is recommended that:
• The alignment stars chosen should always
be at 30 to 80 degrees in altitude and
separated by at least 70 degrees in
azimuth.
• Alignment stars should ideally have at
least a few degrees separation in altitude
• Polaris can be used as one of the
alignment stars
To achieve the best pointing accuracy on an
Equatorial mount it is recommended that:
• Polaris should never be used as one of the
alignment stars
• Alignment stars with a declination greater
than 80 degrees should be avoided
• The alignment stars chosen should always
be at 30 to 80 degrees in altitude and
separated by at least 70 degrees in RA.
