Description

Antares sells a variety of adapters/bushings to attach GSO-style Crayford focusers to many telescopes. It is a trivial matter to remove the base plate from a GSO focuser and insert the focuser into any one of the adapters below using a small allen key (not included). The telescope side of these adapters has three screw holes to attach the assembly to your telescope tube (except the SCT adapter). All adapters are machined out of aluminum and anodized black.
