Orion 5521 Deluxe Off-Axis Guider for Astrophotography
Orion's Deluxe Off-Axis Guider lets you image and guide simultaneously through the same astrophotography telescope, eliminating the need for a separate guide scope
Eliminates tracking problems caused by using a separate guide scope such as differential flexure and mirror shift, and also helps reduce imaging setup time and overall weight
Compatible with astrophotography autoguiders that feature T-threads or a 1.25" nosepiece, as well as 1.25" illuminated reticle eyepieces
Attaches to any 2" telescope focuser via the included 2" nosepiece, or onto any T-thread equipped rear-cell. Includes T-extensions of three different lengths (7mm, 17mm, and 30mm) to accommodate different camera/guider combinations
Features prism tilt adjustment and more than 100 degrees of radial adjustment for easy guide star location. Requires a minimum of 59mm inward focus travel
Designed for deep-sky imaging with Schmidt-Cassegrain and refractor telescopes, the Orion Deluxe Off-Axis Guider lets you image and guide simultaneously through a single telescope. This also eliminates tracking problems such as differential flexure and mirror shift that commonly occur when using a separate guide scope. The imaging camera sees the same movement the autoguider sees, resulting in highly accurate tracking for pinpoint stars. Prism tilt adjustment with captive thumbscrew and more than 100 degrees of radial movement allow for easy guide star acquisition. Coarse and helical fine focus adjustments make focusing easy and accurate. The Orion Deluxe Off-Axis Guider can be used with most imaging cameras, including DSLRs, and telescopes with sufficient inward focus travel (requires 59mm). Three different lengths of threaded T-extensions are included (7mm, 17mm, 30mm) to accomodate different camera/guider combinations. Not recommended for use with Newtonian reflectors due to their limited focus travel. One-year warranty.
