80mm Wide View Spotting Scope (#52260) 102mm Wide View Spotting Scope (#52270) INSTRUCTION MANUAL
INTRODUCTION A spotting scope is nothing more than a telescope that is designed to look around the Earth. Unlike astronomical telescopes, which produce inverted or reverted images, spotting scopes produce correctly oriented images. 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 ongoing use.
GETTING STARTED The high magnification of your spotting scope makes it very difficult to handhold and, as a result, it must be attached to a stable platform. The 102mm Wide View has a tripod adapter block, which is located on the bottom of the spotting scope tube. Remove your spotting scope from the box and attach it to any of the mounts described below.
The Wide View Spotting Scope This section covers the correct set up and operating procedures for your Celestron 80mm or 102mm Wide View spotting scope and includes information on visual and photographic observations. The Wide View spotting scope uses a classical refractor optical design with a twoelement (achromatic) lens made of crown and flint glass. Unlike other spotting scopes which have built-in correcting prisms, the Wide View uses a diagonal to produce a correctly oriented image.
Removing the Lens Cover To protect your spotting scope, the objective lens, focuser, and accessories are fitted with protective covers. All are tension-fitted and easily removed by pulling off. The covers should be removed as each piece is installed. Once removed, place the covers in the box to ensure they won’t get lost. Attaching the Standard Accessories With your spotting scope attached to a sturdy mount, as described earlier in this manual, you are ready to attach the standard accessories.
presses tightly between the finderscope and the inside of the bracket. Tighten the three adjustment screws until they make contact with the finderscope body. See figure 3a. 2. Slide the finder bracket (attached to the finderscope) into the mounting bracket on the spotting scope. Tighten the thumb screw on the mounting bracket to hold the finderscope in place. See figure 3b. Finderscope Adjustment Screws Figure 3a Figure 3a Figure 3b Aligning the Finderscope To align the finderscope: 1.
Focusing For objects closer than the one you are currently observing, turn the focus knobs towards the eyepiece and for objects further away, turn the focus knobs away from the eyepiece. Changing Eyepieces You can vary the power of your spotting scope simply by changing eyepieces. To change eyepieces: 1. Loosen the thumbscrew on the 45° Erect Image Diagonal. 2. Remove the eyepiece currently in the spotting scope. 3. Insert a new eyepiece into the 45° Erect Image Diagonal. 4.
Attaching a Camera To attach a camera to your Wide View Spotter: 1. Remove all visual accessories. 2. Thread the proper T-Ring onto the built-in T-Adapter threads at the end of the eyepiece holder. 3. Mount your camera body onto the T-Ring the same as you would any other lens. Focusing The Camera The focusing mechanism is the same photographically and visually. However, due to the high magnification, the micro prism focuser in your camera may "black out.
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. S 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.
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 True Field (in degrees) = Magnification Using the example we started with in the previous section, we can determine the field of view using the same 25mm eyepiece.
ASTRONOMY WITH YOUR SPOTTING SCOPE A spotting scope is nothing more than a telescope that produces correctly oriented images. That is why all Celestron spotting scopes are so well-suited for looking around the Earth. But this in no way limits the spotting scope to terrestrial use. On the contrary, the 102mm Wide View spotting scopes work well as an astronomical telescope for observing the sky. Observing the Sun Although overlooked by many amateur astronomers, solar observation is both rewarding and fun.
Observing Deep Sky Objects Deep sky objects are simply those objects outside the boundaries of our solar system. They include star clusters, planetary nebulae, diffuse nebulae, double stars, and other galaxies outside our own Milky Way. Because your spotting scope is not set up for serious astronomical observing, you will need to know where to look in the sky for these objects. The Celestron Sky Maps (#93722) will help you locate the brightest deep sky objects.
CARE AND CLEANING OF THE OPTICS Occasionally, dust and/or moisture may build up on the lens of your spotting scope. Special care should be taken when cleaning any optical instrument so as not to damage the optics. If dust has built up on the lens, remove the dust with a camel’s hair brush or a can of pressurized air. Spray at an angle to the lens for approximately 2 to 4 seconds.
