Bushnell 78-2010 Telescope User Manual


 
Helpful Hints
1. Your telescope is a very sensitive instrument. For best results and fewer vibrations set your
telescope up on a level location on the ground rather than your concrete driveway or your
wooden deck. This will provide a more stable foundation for viewing, especially if you've
drawn a crowd with your new telescope.
2. If possible view from a location that has relatively few lights. This will allow you to see
much fainter objects. You'd be surprised how much more you'll see from your local lake or
park when compared to a backyard in the city.
3. Using your telescope out a window is NEVER recommended.
4. View objects that are high in the sky if possible. Waiting until the object rises well above the
horizon will provide a brighter and crisper image. Objects on the horizon are viewed
through several layers of earth's atmosphere. Ever wonder why the moon appears orange as
it sets on the horizon. It's because you are looking through a considerable more amount of
atmosphere than you would directly overhead. (Note: If objects high in the sky are distorted
or wavy, you are probably viewing on a very humid night.) During nights of unstable
atmosphere, viewing through a telescope can be frustrating if not impossible. Astronomers
refer to crisp, clear nights as nights of "good seeing."
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.
