Optional Tripod

For extra steady views or for doing photography, it is recommended that you use a medium/heavy duty photo/video tripod.

Using the Rubber Eyecup

The zoom eyepiece includes a soft rubber eyecup for eyeglass wearers. Fold down the rubber eyecups to observe the full field of view

when wearing eyeglasses. If you do wear eyeglasses, leave the rubber eyecup in the up position.

Before Looking Through Your Spotting Scope --- A Word of Caution!

Never look directly at the Sun with the naked eye or with your spotting scope. Permanent eye damage may result.

Observing with your Spotting Scope

You can use the sight tube to locate the area of the object you want to look at. Then rotate the zoom eyepiece to 25x (which is the

lowest power). Rotate the magnification ring around the zoom eyepiece to change the power level of the spotting scope. Refocus as

needed. The brightest and widest field of view will always be at the lowest power.

Focusing

To focus, slowly rotate the focuser knob until the image in the eyepiece is clear and sharp. Refocusing is usually required if the power

is changed. If you feel the focus knob no longer moves any further (in either direction), then you have reached the end of the travel

range -- don't try to force it to go further but you should refocus by turning in the opposite direction. Once an image is in focus, turn

the knob clockwise to focus on a closer object and counterclockwise for a more distant object.

Photography with Digital Cameras

You can use your digital camera (and some 35mm SLR cameras) to take photos with your spotting scope. Celestron offers a

Universal Digital Camera Adapter (Model # 93626) which makes it easy to attach a digital camera to your C50 Mak spotting scope.

Follow your cameras instructions for exposure information, etc. You will have to experiment to get the settings correct.

1.25" Eyepiece Adapter

This adapter is included with your spotting scope. It allows you to use astronomical 1.25" eyepieces so you can have various powers

and wider fields of view for specific usages. To install the adapter, you will remove the zoom eyepiece (turn it hard counterclockwise

to unthread it), thread the 1.25" adapter where the zoom eyepiece goes, then put your 1.25" eyepiece into the adapter and tighten the

thumb screw to hold the eyepiece in place. The pictures left to right below demonstrate the assembly.

Maintenance

To protect your spotting scope when not being used, put on all lens covers to keep the optics clean and then put the scope in the soft

carrying case. If your optics need cleaning, use an optics cleaning kit and follow the instructions.
