If you own an SCT this is a great way to reduce the weight on the mount, and overcome some or most of the mirror flop/movement issues.
No, it isn't the magic bullet, but close to it.
Screws onto the rear cell, and accepts a camera ring etc on the other end.
Guiding section is partly rotatable which allows a radial search for a guide-star, and the pick-off prism is adjustable up and down, as well as for tilt. A by far and away better system than the straight fixed pick-off prism.
Has a 1.25" opening to accept a guide camera or guiding eyepiece.
Near new, and in excellent condition. With original box.
New/retail, at York, these are AU$249.
This one AU$150, plus post.
