Celestron offers several different models, each of which uses the highest quality optics to produce the best possible images. How to Use this Manual This manual explains the proper use of your Celestron spotting scope —from initial set up to on- goi

Photographic Tripod For best results, attach your Celestron spotting scope to a heavy duty photo tripod with a quick release platform. To attach

VISUAL OBSERVING INFORMATION Focusing When working with any optical instrument, there are several focusing hints that will ensure that you get the sharpest possible image. The hints listed here are for visual observing and photography. Never look through glass. Glass found in household windows is optically imperfect and may vary in thickness from one location to the next. This inconsistency can and will affect the ability to focus your spotting scope. In most cases, you will not

Field of View Determining the field of view is important if you want to get an idea of the size of the object you are observing. To calculate the actual field of view, divide the apparent field of the eyepiece (supplied by the eyepiece manufacturer) by the magnification. In equation format, the formula looks like this: Apparent Field of Eyepiece (in degrees) True Field (in degrees) = Magnification Using the example we started with in the previous section, we

ASTRONOMY WITH YOUR SPOTTING SCOPE A spotting scope is nothing more than a telescope that produces correctly oriented images. That is why all Celestron telescopes and spotting scopes are so well-suited for looking around the Earth. But this in no way limits a spotting scope to terrestrial use.

Photographing the Moon After looking at the night sky for awhile you may want to try photographing it. If you do, start with a nice, bright object like the Moon. To photograph the Moon: 1. Attach your spotting scope to a stable platform like the Celestron Photographic Tripod (#93596). 2. Load your camera with film that has a moderate-to-fast speed (i.e., high ISO rating). Faster films are more desirable when the Moon is a crescent. When the Moon is full, and at its brightest, slower
