Bushnell 78-9675 - Manual (Page 6)

Where do I start?
Your Bushnell telescope can bring the wonders of the universe to your eye. 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. The first thing you need to do is get 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. Some views of brilliant Venus appear 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.

ANSWERS TO COMMONLY ASKED QUESTIONS
1. The image I see in the telescope is upside down and
reversed from right to left ?
• An upside-down and reversed image is a common
characteristic of most astronomical telescopes. Since
telescopes are used for astronomical viewing
orientation is not important. The image in the
finderscope will also be upside down and reversed.
2. How do I determine the power my telescope ? • The power of your telescope can be determine by
dividing the focal length of the objective lens by the
focal length of the eyepiece. The eyepiece focal length
is the number printed on the eyepiece. (For example:
1000
÷ 25 = 40X)
3. Where do I find the Telescope Focal Length • The telescope focal length is the same focal length as
the objective focal length. For this telescope it is
900mm. Telescope focal lengths range from 600mm
to 900mm on Bausch & Lomb, Bushnell and Jason
telescopes.
4. What can I see with my telescope ? • Telescopes with power ranging from 25X to 50X can
