ZWO Off Axis Guider OAG

NEW from ZWO Thin Off Axis Guider that allows you to Autoguide in SCTs and Refractors whilst only adding 16.5mm to the optical path.

Features a precision 8mm x 8mm  prism,  it comes complete with M48 and T2 adapters  to the scope and M42 and M48 adapters to camera to keep back focus to a minimum, a 5mm spacer for guide cameras where the back focus is only 12.5mm.

Compatible with all ZWO ASI cameras.

A must for Cassegrain OTA’s. No guide scope therefore no differential flexure between Guide scope and main telescope.
