ongratulations! Your Orion Sky Wizard Model 3 will put the fun back in your telescope observing. It provides a

digital readout of celestial coordinates, a database of more than 10,000 of the most interesting deep sky subjects,
and the ability to guide the observer to astronomical objects. It’s designed to work with both altazimuth (including
Dobsonian) and equatorial telescope mounts. The catalog information is stored in permanent internal memory. The
celestial subjects are organized by catalog: Messier (M), NGC and IC, plus other lesser known catalogs. Many
interesting stars are in the ST (Star) list. You can add up to 27 objects in your own NEW catalog.
Sky Wizard is designed for ease of use. Simply turn it on, sight two stars, and let it guide you to celestial objects.
There is no need to polar align the telescope, input latitude, longitude, date or time (date needed for planets). It
provides virtually any telescope with a continuous digital display of celestial coordinates. The unique method of
alignment by two star sightings provides good pointing accuracy over the entire sky.
Finding an object is easy. Just select any subject from one of the catalogs and tell Sky Wizard to find it by using
the FIND function. The display will then give instructions on how to move your telescope. You can also point your
telescope at any object in the sky, with the IDENTIFY mode, Sky Wizard will search its database and tell you the
object’s identity.
At the beginning of each observing session, you align Sky Wizard with the current sky by selecting a bright star
from the SETUP menu (list of the brightest navigational stars), pointing the telescope at that star, and then press-
ing ENTER when the star is centered in the eyepiece. The procedure requires sighting on only one star for a
polar-aligned equatorial mount, but sighting a second star will improve accuracy. An altazimuth telescope requires
two star sightings for alignment. Additional sightings made during the observing session reduce cumulative errors.
Sky Wizard weighs only 8 ounces, including the internal battery, and may be conveniently mounted near the eye-
piece. Sky Wizard connects electrically to the optical encoders with a plug-in connecting cable. The red LED display
is easy to read and does not interfere with night-adapted vision. A dimming button adjusts the brightness of the
display. Sky Wizard is especially useful under light-polluted skies where few visible stars are available to guide you
to deep-sky objects.
Sky Wizard is connected to your telescope with optical encoders. The encoders sense the rotation of the telescope
within 0.09° or 0.17°, which is precise enough to bring any object into a low-power field of view, and can track
telescope motion at rates as high as 160° per second. The encoders are attached by various methods depending
on your telescope model. Installation kits and encoders are sold separately from Sky Wizard to allow for this varia-
tion in attachment method. Instructions for mechanical installation of encoders are provided with the installation
kits.
Powered by a single 9-volt alkaline battery, Sky Wizard provides over 24 hours of operation with the display fully
dimmed. It can also operate from an external 12-volt DC power supply connected to the battery snap.
