68 mm guide scope ring pair with mini dovetail bar provides stable and precise mounting for guide scopes in astrophotography and autoguiding systems. The rings are compatible with guide scopes with an outer tube diameter of approximately 45–66 mm.
The adjustment screw design allows the guide scope to be aligned slightly differently from the main telescope’s field of view, making it easier to select a suitable guide star. Plastic inserts in the tube mounting screws protect the tube from scratches.
The tube rings and mini dovetail bar are made of anodized aluminium alloy, providing sufficient rigidity and durability while keeping weight low. The rings feature M5 threaded holes.
The included mini dovetail bar is 90 mm long and 31 mm wide and can be mounted in a finder scope shoe. It also features a 1/4" photo tripod thread and two M8 threaded holes in the centre.
