Welcome to a new world of adventure. Your new StarMax 102mm EQ is designed for high-resolution observing of astronomical objects, and can also be used for terrestrial exploration. With its precision optics and equatorial mount, you’ll be able to locate and enjoy hundreds of fascinating celestial objects, including the planets, Moon, and a variety of deep-sky galaxies, nebulas, and star clusters. -

3. Assembly Assembling the telescope for the first time should take about 30 minutes. No tools are needed other than the ones provid- ed. All bolts should be tightened securely to eliminate flexing and wobbling, but be careful not to over-tighten or the threads may strip. -
Page 5: Getting Started
The telescope system is now fully assembled. Keep the dust cover over the front end of the telescope when it is not in use. It is also a good idea to cover the eyepiece; use the cover cap that came with it. - Page 6 The telescope is now balanced on the R.A. axis. It is not nec- essary to balance the telescope on the Dec. axis, since the optical tube’s mounting block is positioned so that the tele- scope will automatically be balanced on that axis. Now when...

(from west to east). An equatorial mount (Figure 2) is designed to compensate for that motion, allowing you to easi- ly “track” the movement of astronomical objects, thereby keeping them from drifting out of the telescope’s field of view while you’re observing.

So, the coordinates for the Orion Nebula listed in a star atlas will look like this: R.A. 5h 35.4m Dec. -5° 27' That’s 5 hours and 35.4 minutes in right ascension, and -5...
- Page 9 1 the telescope is pointed north, as it would be during polar alignment. The counterweight shaft is oriented downward. But it will not look like that when the telescope is pointed in other directions. Let’s say you want to view an object that is directly overhead, at the zenith.

Eyepiece Selection By using eyepieces of varying focal lengths, it is possible to attain many magnifications with the StarMax 102mm EQ. The telescope comes with one high-quality 25mm Sirius Plossl, which gives a magnification of 52x. Other eyepieces can be... - Page 11 Sky & Telescope, or other astronomy magazines. Venus, Mars, Jupiter, and Saturn are the brightest objects in the sky after the Sun and the Moon. Your StarMax 102mm EQ is capable of showing you these planets in some detail. Other planets may be visible but will likely appear star-like.
- Page 12 Star hopping, as it is called by astronomers, is perhaps the simplest way to hunt down deep-sky objects to view in the night sky. It entails first pointing the telescope at a bright star close to the object you wish to observe, and then progressing to other stars closer and closer to the object until it is in the field of view of the eyepiece.

Also keep the finder scope caps on if you leave it attached to the optical tube. Cleaning the Tube Your StarMax 102mm EQ telescope requires very little mechanical maintenance. The optical tube is aluminum and has a smooth painted finish that is fairly scratch-resistant. If a scratch does appear on the tube, it will not harm the tele- scope. -

Then apply some cleaning fluid to a tissue, never directly on the optics. Wipe the lens gently in a circular motion, then remove any excess fluid with a fresh lens tissue. Oily finger- prints and smudges may be removed using this method. Use caution;... - Page 16 During this warranty period Orion Telescopes & Binoculars will repair or replace, at Orion’s option, any warranted instrument that proves to be defective, provided it is returned postage paid to: Orion Warranty Repair, 89 Hangar Way, Watsonville, CA 95076. If the product is not registered, proof of purchase (such as a copy of the original invoice) is required.
- Page 17 Try to keep your eye centered with respect to the rear opening of the tube as best as possible. Using an Orion Collimating Eyepiece will aid greatly in keeping your eye cen- tered and is strongly recommend.
