Starlight Xpress Super-Slim Off-Axis Guide Head w/Adapters

PRICE: 345.00

Starlight Xpress Super-Slim Off-Axis Guide Head w/Adapters Description

The Starlight Xpress SX-OAG is ideal for off-axis guiding with a variety of cameras and telescopes. This version can be used without the Starlight Xpress filter wheel, so is ideal for almost any system.

There are several options available. You can choose the adapter for the telescope side of the OAG, the adapter for the camera side of the OAG, and the length of the extension behind the OAG. The extension is required to take up the extra distance when not using the SX filter wheel. Please call us with any questions on the best setup for your telescope and camera.
