WHERE DO I START?

Your Bushnell telescope can bring the wonders of the universe to your eyes. While
this manual is intended to assist you in the set-up and basic use of this instrument,
it does not cover everything you might like to know about astronomy. It is
recommended you obtain a very simple star chart and a flashlight with a red bulb
or red cellophane over the end. For objects other than stars and constellations, a
basic guide to astronomy is a must. Some recommended sources appear on our
website at www.bushnell.com. Also on our website will be current events in the sky
for suggested viewing. But, some of the standbys that you can see are:

The Moon—A wonderful view of our lunar neighbor can be enjoyed with any
magnification. Try viewing at different phases of the moon. Lunar highlands, lunar
maria (lowlands called "seas" for their dark coloration), craters, ridges and
mountains will astound you.

Saturn—Even at the lowest power you should be able to see Saturn’s rings and
moons. This is one of the most satisfying objects in the sky to see simply because
it looks like it does in pictures. Imagine seeing what you’ve seen in textbooks or
NASA images from your backyard!

Jupiter—The largest planet in our solar system is spectacular. Most noted features
are its dark stripes or bands both above and below its equator. These are the north
and south equatorial belts. Also interesting are Jupiter’s four major moons. Pay
close attention to their positions from night to night. They appear to be lined up on
either side of Jupiter.

Mars—The Great Red Planet appears as a reddish-orange disk. Look at different
times of the year and try to catch a glimpse of the white polar ice caps.

Venus—Just like the moon, Venus changes phases from month to month. At times
Venus appears brilliantly in the night sky, just as if you were looking at a distant crescent
moon.

Nebulae—The Great Orion Nebula is a very well known night sky object. This and many
others are brought to you by this telescope.

Star Clusters—View millions of stars densely packed in a cluster that resembles a ball.

Galaxies—One of the greatest and most interesting galaxies is our neighbor, the

Andromeda Galaxy. Enjoy this and many others.
