Bausch & Lomb 78-0045 Telescope User Manual


 
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 Bausch & Lomb 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 changed 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.
Much, much, more!
