This section covers the assembly instructions for your Travel Scope. Your telescope should be set up indoor the first time so that it is easy to identify the various parts and familiarize yourself with the correct assembly procedure before attempting it outdoor. The Travel Scope comes in one box. The pieces in the box are – telescope optical tube, tripod, erect image diagonal, 20mm eyepiece, 10mm eyepiece, 5x24 Finderscope with bracket ----- all packed in the travel backpac

Installing the Diagonal & Eyepiece Installing the Diagonal & Eyepiece The diagonal is a prism that diverts the light at a right angle to the light path of the telescope. This allows you to observe in a position that is more comfortable than if you had to look straight through. The Travel Scope 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

Focusing Focusing To focus your Travel Scope turn the focus knob located near the rear of the telescope (see Figure 1-1). Turning the knob counterclockwise allows you to focus on an object that is farther than the one you are currently observing. Turning the knob clockwise from you allows you to focus on an object closer than the one you are currently observing. Note: Remove the front lens cap of the Travel Scope optical tube prior to attempting your observation. Note

Determining Field of View Determining Field of View Determining the field of view is important if you want to get an idea of the angular 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 Angular Field = ⎯ ⎯⎯ ⎯⎯⎯⎯ ⎯⎯ ⎯⎯⎯⎯ Magnification As you can see, before determ

Up to this point, this manual covered the assembly and basic operation of your telescope. However, to understand your telescope more thoroughly, you need to know a little about the night sky. This section deals with observational astronomy in general and includes information on the night sky. The Celestial Coordinate System The Celestial Coordinate System To help find objects in the sky, astronomers use a celestial coordinate system that is similar to our geographical co- ord

Motion of the Stars Motion of the Stars The daily motion of the Sun across the sky is familiar to even the most casual observer. This daily trek is not the Sun moving as early astronomers thought, but the result of the Earth's rotation. The Earth's rotation also causes the stars to do the same, scribing out a large circle as the Earth completes one rotation. The size of the circular path a star follows depends on where it is in the sky. Stars near the celestial equator form the larg

With your telescope set up, you are ready to use it for observing. This section covers visual observing hints for 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 phas

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

Star hopping will take some getting used to and objects that don’t have stars near them that are visible to the naked eye are challenging. One such object is M57 (Figure 5-2), the famed Ring Nebula. Here's how to find it: 1. Find the constellation of Lyra, a small parallelogram visible in the summer and fall months. Lyra is easy to pick out because it contains the bright star Vega. 2. Start at the star Vega—Alpha ( α) Lyrae—and move a few degrees southeast to find the parallelog

S Se ee eiin ng g C Co on nd diit tiio on ns s Viewing conditions affect what you can see through your telescope during an observing session. Conditions include transparency, sky illumination, and seeing. Understanding viewing conditions and the effect they have on observing will help you get the most out of your telescope. Transparency Transparency is the clarity of the atmosphere which is affected by clouds, moisture, and other airborne particles. Thick cumulus clouds

While your telescope requires little maintenance, there are a few things to remember that will ensure your telescope performs at its best. Care and Cleaning of the Optics Care and Cleaning of the Optics Occasionally, dust and/or moisture may build up on the objective lens of your telescope. Special care should be taken when cleaning any instrument so as not to damage the optics. If dust has built up on the optics, remove it with a brush (made of camel’s hair) or a can of
