73991 GPD2 Equatorial Mount
A high precision equatorial mount suitable for long exposure astrophotography
The GPD2 equatorial mount has the same compact design as the GP2 mount but benefits from additional features and higher maximum payload weight.
The RA and DEC axes are made of steel and the worm wheels are made of brass for durability. Both the RA and DEC worm screw gears are machined to a very precise tolerance to minimise periodic error.
The mount comes equipped with polar axis scope with a built-in variable intensity illuminator.
Accepts payloads up to 10kg.
Product features
Accurate polar alignment
The mount includes setting circles to position Polaris within the eyepiece field of view.
Built in polar scope
The 6x20mm polar axis scope can be used in both the northern and southern hemispheres.
There is a built-in variable intensity illuminator for the polar axis scope.
Motor drive upgrade
Either the D2M motor controller set or the Star Book S system for GO-TO slewing and celestial tracking can be added to the mount.
