Some of the terms and parts described in these instructions may be new to you, so a few commonly used terms you’ll want to be familiar with are defined below. Altazimuth mount - the simplest type of mount, with two motions: altitude (up and down) and azimuth (side-to-side). “Mount" refers to the part of the telescope that supports the tube, which carries all the telescope’s optics. Altitude lock - allows the telescope tube to be locked into place once a focused image has been set up, by tighte

Nota: cuando pulse el boton se encendera una luz LED indicadora situada encima del ocular. La potencia menor le ofrecera la mejor imagen y el campo visual mas amplio. Para visualizar a una potencia mayor, pulse el boton 24x y mantengalo pulsado hasta que llegue a la potencia deseada (entre 9x y 24x). Nota: al utilizar este boton tambien se encendera una luz LED. Las potencias mayores se utilizan para acercar con el zoom el objeto que esta mirando. Al alcanzar una potencia mayor con el zoom tendr

If you find that the ring pattern is skewed in a different direction, than simply repeat steps 2 through 6 as described above for the new direction. Perfect collimation will yield a star image very symmetrical just inside and outside of focus. In addition, perfect collimation delivers the optimal optical performance specifications that your telescope is built to achieve. Figure 8-3 A collimated telescope should appear symmetrical with the central obstruction centered in the star's diffraction pa

There are several methods of polar alignment, all of which work on a similar principle, but are performed somewhat differently. For each hemisphere, there is a point in the sky around which all the other stars appear to rotate. These points are called the celestial poles and are named for the hemisphere in which they reside. For example, in the northern hemisphere all stars appear to move around the north celestial pole (see figure 6). When the telescope’s polar axis is pointed at the celestial

Tighten the screw completely. 5. Repeat this process for the remaining two comers of the accessory tray. Setting up the Aluminum Tripod If your model has the Aluminum Tripod: 1. Attach the legs to the tripod head as above. 2. Spread the leg apart. 3. Attach the accessory tray to the leg braces. 5 SETTING UP THE TELESCOPE Orienting the Telescope 1. Begin by identifying and loosening knobs #16, 22, 24 and 28, using the diagram in Figure 1 to guide you. 2. Next, rotate the telescope opti

Call Celestron at 310-328-9560 to receive the number to be displayed on the outside of your shipping container. All returns must be accompanied by a written statement setting forth the name, address and daytime telephone number of the owner, together with a brief description of any claimed defects. Parts or product for which replacement is made shall become the property of Cl. The customer shall be responsible for all costs of transportation and insurance, both to and from the factory of Cl, a

This also holds true for adults who may not be familiar with the correct operating procedures for your telescope. ALWAYS cover the finderscope when using your telescope with a correct solar filter. Although small in aperture, this instrument has enough light gathering power to cause permanent and irreversible eye damage. The image projected by the finderscope is hot enough to bum skin or clothing. THE REFRACTOR TELESCOPE Your telescope is a classical, two element refracting telescope that com

The C102-AZ is similar to the Firstscope AZ and all text referred to in this manual on the Firstscope AZ applies equally to the C102-AZ. The telescope is shipped in one box which contains the optical tube, altazimuth mount and all the standard accessories, which include: Unpacking Your Firstscope AZ Setting Up the Aluminum Tripod ’ 25mm SMA Ocular 1-1/4" (36x) - with 70mm and 80mm models ■ 6mm F Ocular 1-1/4" (150x) - with 70mm only ’ 20mm Plossl Ocular 1-1/4” (50x) - with 102mm only ■ 6x3

There are various types of eyepieces of varying quality to choose from. B. Magnification through the telescope has its limits. These limits are determined by the laws of optics and the nature of the human eye. The maximum usable power is equal to 60 times the aperture of the telescope (in inches). So your telescope has a maximum useful power of 180x (3" x 60). If you purchased the 114mm model (4.5") then your maximum useful power is 270x (4.5" x 60). You can create power higher than this limit

This telescope is a precision scientific instrument that will allow you to enjoy viewing numerous objects in the night sky — planets, nebulae, star clusters, galaxies and more. Before embarking upon an exploration of the sky, please take time to read this manual and familiarize yourself with both the parts and operation of your telescope. WARNING NEVER LOOK DIRECTLY AT THE SUN WITH THE NAKED EYE OR WITH A TELESCOPE. NEVER ■POINT YOUR TELESCOPE AT THE SUN UNLESS YOU ARE USING THE PROPER SOLAR
