Congratulations on your purchase of the Orion Deluxe
Off-Axis Guider.
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 flex-
ure or mirror shift. Since the autoguider detects the exact
same movement as the imaging camera, you are assured
highly-accurate tracking.

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 accom-
modates nearly any imaging cam-
era and autoguider. We recommend
using a compact autoguider, such
as the StarShoot AutoGuider; how-
ever 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.

Autoguider spacing
The imaging camera and autoguider
must come to the same focus point
to successfully operate the Deluxe
Off-Axis Guider. The imaging chip in
your CCD or DSLR camera and the
detector in your autoguider must be equidistant to the focal plane of your tele-
scope. 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 configu-
ration 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.
