IIn ns st ta alllliin ng g t th he e D Diia ag go on na all The diagonal is a prism that diverts the light at a right angle to the light path of the refractor. This allows you to observe in a position that is more comfortable than if you looked straight through. This diagonal is an erect image model that corrects the image to be right side up and oriented correctly left-to-right which is much easier to use for terrestrial observing. Also, the diagonal can be rotated to any positio

3 Center your target in the main optics of the telescope. You may have to move the telescope slightly to center it. 4 Adjust the screw on the side of the finder bracket until the cross hairs are centered horizontally on the target seen through the telescope. 5 Adjust the screw on the top of the finder bracket until the cross hairs are centered vertically on the target seen through the telescope.

A telescope is an instrument that collects and focuses light. The nature of the optical design determines how the light is focused. Some telescopes, known as refractors, use lenses, .and other telescopes, known as reflectors (Newtonians), use mirrors. Developed in the early 1600s, the refractor is the oldest telescope design. It derives its name from the method it uses to focus incoming light rays. The refractor uses a lens to bend or refract incoming light rays, hence the name

Magnification = ⎯ ⎯⎯⎯ ⎯⎯⎯⎯ ⎯⎯ ⎯⎯⎯⎯ Focal Length of Eyepiece (mm) Let’s say, for example, you are using the 10mm eyepiece that came with your telescope. To determine the magnification you simply divide the focal length of your telescope (the SkyScout Scope for this example has a focal length of 660mm) by the focal length of the eyepiece, 10mm. Dividing 660 by 10 yields a magnification of 66 power. Although the power is variable, each instrument under average skies has a l

With your telescope set up, you are ready to use it for observing. This section covers visual observing hints for both solar system and deep sky objects as well as general observing conditions which will affect your ability to observe. Observing the Moon Observing the Moon Often, it is tempting to look at the Moon when it is full. At this time, the face we see is fully illuminated and its light can be overpowering. In addition, little or no contrast can be seen during this phase

Observing Deep Sky Objects 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. Most deep-sky objects have a large angular size. Therefore, low-to-moderate power is all you need to see them. Visually, they are too faint to reveal any of the color seen in long exposure photographs. Instead, they appear
