Editorial Reviews
Product Description:
Specifically for use in prime focus, deep-sky imaging or astrophotography with Schmidt-Cassegrain telescopes, the Radial Guider is compact and sleek in design. This accessory makes it possible to simultaneously photograph and guide through the optical tube assembly of your telescope. The Radial Guider also eliminates the problem of differential flexure, because you're both guiding and photographing through the telescope. The Radial Guider is compatible with Celestron's C5, C8, C9¼, C11 and C14 telescopes and comes with a unique prism angle adjustment screw. It must be used with a guiding eyepiece, camera T-Ring and drive corrector (dual axis preferred). Primarily for use with catadioptric telescopes, but also works on refractor telescopes having adequate back focus. 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°.

Content: The small side prism delivers substantially more luminiscent imaging of the fainter stars than one could actually expect. However, manual guiding might be a real challenge, especially, should your option is limited by Alt-Az GoTo mount. Therefore I suggest to get prepared to study auto-guiding software and test your RS-232 port communication. Also, in order to use Canon EOS 300...450 models, you need to obtain additional extender ring, because the radial guider's winding-in will be obstructed by the dimentions of the built-in EOS flash.
Summary: Nice add-on to your deep sky photoset

Content: Nice concept. I own 5 telescopes including one schmidt cassegrain. This won't fit or work with any of them. So I wasted my money buying it. But it sure seems like a neat concept...too bad.
