This mount can be used either with one or with two telescopes. When it is equipped with telescopes of under 6 kg one can well work without counterweights.
When using heavy telescopes, you can fix a counterweight bar and a counterweight on the GR-3 on the side opposite the telescope.
The telescope and its centre of gravity may, as usual, be balanced most exactly by shifting it in the tube holders. By upgrading the mount with our prism clamp, you can also use telescopes with prism rails.
The new GR-3 DX is made of high-strength aluminium alloy and manufactured on the latest CNC machines. The mount can easily be fixed on almost every tripod.
The GR-3 DX mount sets itself apart by the new radial/axial bearing (free of lubricant). In its interior, high-quality sliding-contact bearings act against the rotation movement and the well-known side load. The finish as well as the cosmetic changes enhance the look of this new mount. This mount is serially anodised in red.
Like the GR-2, the GR-3 DX may, against extra charge, be upgraded by accessories like a counterweight bar plus counterweight or the Tele-Optic mounting plate D-3. By equipping the mount with an additional bracket, the GR-3 DX becomes the GR-3 TV (twinview). This model permits using two telescopes simultaneously, a useful upgrade, which makes itself paid particularly at guided star tours at observatories or when comparing optics.
