Celestron radial off-axis guider. Screws onto rear of Mead and Celestron Schmidt-Cassegrain telescopes. Very nice entry-level off-axis guider.
"This guider is a tremendous improvement over conventional off-axis guilders. Not only is the angle of the prism tunable, but it also maintains a fixed rigid camera orientation while still offering users the freedom to move the guiding eyepiece radially about 135°."
Very good condition. $50 + $5 Shipping.
Pay Pal preferred. Money Order OK. Continental US only
