About this product
This new accessory for the Starlight Xpress filter wheel is perfect for accurate, flexure-free guiding.
The 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 SX H18 and M26 cameras is also available (not suitable for other SX cameras as the OAG cannot achieve focus for these, without the camera adaptor in place).
The optional variable 20mm guide head extender is useful when using non-Starlight Xpress guide or imaging cameras to ensure both cameras can be brought into focus at the same time.
