Starlight Xpress Ultra Slimline Axial Guide Accessory Kit For Use With SX Filter Wheel & Lodestar/SXV/SXV-EX Autoguider With Extension

NEW! Super-Slim Off-Axis guide head add-on

This new filter wheel accessory makes accurate, flexure-free guiding easy to achieve. The extremely slim assembly screws directly to the wheel face and adds only 13mm to the back focal distance of the wheel. The 10 x 8mm prism fully illuminates a Lodestar or EX guider CCD and the pick-off axis may be adjusted to optimise the guide image quality. An alternative filter wheel face plate for direct attachment of our H18 and M26 cameras is also available [20704] (not suitable for other SX cameras as the OAG cannot achieve focus for these, without the camera adaptor in place)
