. . . . . . . Figure 1a. Congratulations on your purchase of the Orion Deluxe Off-Axis Guider. This useful imaging accessory enables you to image and guide through the same telescope, thereby eliminating the need for a separate guide scope which also saves weight on your mount. The Deluxe Off- Axis Guider is especially useful for Schmidt-Cassegrain telescopes or other systems that are prone to optical flexure or mirror shift. Since the autoguider detects the exact same movement as the imaging camera, you are assured highly-accurate tracking. Parts list 1.

Getting started The Deluxe Off-Axis Guider comes with all of its parts already attached; however, you should remove the parts first because you may not have to use all of them to guide with your particular telescope, camera, and autoguider. Please take a moment to familiarize yourself with the parts (Figure 1a and 1b). The Deluxe Off-Axis Guider accommodates nearly any imaging camera and autoguider. We recommend using a compact autoguider, such as the StarShoot AutoGuider; however many other autoguider cameras with a 1.25" nosepiece or female T-threads are also appropriate. You can also use any 1.25" eyepiece to help visually locate a guide star before attaching the autoguider. Manually guiding with a 1.25" reticle eyepiece is possible too. setting the correct imaging camera and Autoguider spacing Prism tilt adjustment screw Course focus height adjustment T-threads lock thumbscrews Pick-off prism Radial adjustment lock thumbscrew The imaging camera and autoguider Figure 1b. The main body of the Deluxe must come to the same focus point Off-Axis Guider contains the guiding end to successfully operate the Deluxe which enables guide star acquisition and Off-Axis Guider. The imaging chip in focus. your CCD or DSLR camera and the detector in your autoguider must be equidistant to the focal plane of your telescope. Three extension pieces (30mm, 17mm, and 7mm) are included to allow you to achieve focus with both your imaging camera and autoguider when using the Deluxe Off-Axis Guider. If you are imaging with the StarShoot AutoGuider and the StarShoot Pro, StarShoot Pro V2.0 or a Canon or Nikon DSLR, please refer to Figures 2a-2c for the suggested Deluxe Off-Axis Guider configuration. For any other imaging setup, you must determine the correct spacing configuration to allow your autoguider and imaging camera to reach focus. Keep in mind that the farther away the imaging camera’s chip is from the Deluxe Off- Axis Guider, the farther away the autoguider detector must also be.

Attaching the imaging camera to the Deluxe Off- Axis Guider Once you have estimated what the approximate spacing configuration should be, you are ready to attach the Deluxe Off-Axis Guider to your imaging camera. Simply thread the imaging camera’s female T-threads into the back of the Deluxe Off-Axis Guider (Figure 3). You can optionally use the rotate lock ring to fix the orientation of the Deluxe Off-Axis Guider in relation to the camera. This can be particularly useful for DSLRs because the guider’s radial adjustment sometimes interferes with the camera body. using a starshoot Deep space imaging camera Thread the camera to the Deluxe Off- Axis Guider as shown in Figure 3. 3. Attaching the Autoguider to the Deluxe Off- Axis Guider Thread the fine focus guiding adapter to the guiding end of the Deluxe Off-Axis Guider; then tighten the fine focus lock thumbscrew (Figure 4a). Next, thread the autoguider camera body to the Deluxe Off-Axis Guider (Figure 4b). Figure 3. Thread the imaging camera into the Deluxe Off-Axis Guider. If you are using a DSLR, the T-ring should already be attached to the camera body. Figure 4a. Figure 4b. Figure 5. Use the socket head setscr...
