G53F Friction Drive Mount – German Equatorial

This German Equatorial mount tracks the stars with the highest precision in its category. Based on our Friction Drive System (without gears) is the perfect solution for amateur or professional astrophotographers working in the field and for small to medium observatory use, operated locally or remote.

What are the advantages over the gear worm based system?

Our friction based mounts have no backlash at all, guide perfectly even in DEC, enable longer autoguiding exposures (5-10 sec). Our special wear resistant design keeps its performance over time. All these characteristics and many others together with its low weight make the G53F Friction Drive German Equatorial Mount the ideal astrophotography mount in the field or in the observatory.

Main features of the German Mount G53F

  • Encoder based friction drive system
  • PULSAR 2 based drive system
  • Real Time PEC function to keep the target within cca 1,5″
  • Absolute position reference for recovery after system breakdown

Stable GHS MkII tripod

The GHS MkII tripod remains the ideal solid base for your german mount G53F. It ensures that stability is not compromised by wobbling tripod legs. The MkII model has 8 cm independent leg adjustment (d120x5 mm), central pier (d 60×5 mm),  legs and a legendary stability confirmed by many satisfied customers. The Qlock system saves you a lot of frustration in the dark! You just put the mount head on, turn a handknob on the pier and it’s done. Adjusts between 90-130 cm. The legs fold completely for easy transport and storage . GHS MkII tripod weights is only15 kg!

The geometry and materials of this tripod represent the highgest standard in vibration suppression and torsional stiffness.


Gemini polar scope HP2 – Easy polar alignment

Precise polar aligment in a few minutes? Yes, possible with the original polar scope Gemini HP2! This polar scope uses three stars for alignment for high precision and freedom from reading star charts. You just find the position when the three circles on the reticle match the stars. It is more accurate than traditional “Star Drift” methods. The large 30 mm objective lens lets you see enough stars for a precise alignment. The 12x magnification provides the accuracy needed for GoTo and astrophotography.


Gemini No-Flip pier extension – Uninterrupted astrophotography for compact telescopes

This practical pier extension allows you to take images uninterrupted, even when the object crosses the meridian. Works with refractors up to 5″ or reflectors up to about 10″. The elevation range is 35-50 degree. Adds 390 mm to the pier (241 mm more than the original base) and weights 5 kg. Robust aluminum construction that will not compromise stability. The RA head can be exchanged in 5 minutes between the original and the extended base.
