Slightly loosen the screws that hold the mounting rings on the telescope in place. 2. Slide the rings apart so that each is at the same distance as th e holes in the [...]

2. To move the tel escope in right ascension (east/west) t here are two options. For large and quick m ovements, loosen the right ascension knob when m oving the telescope and t hen tighten the knob when you are near the position you want. For very small m ovements and fi ne adjustments, t urn the right ascension cable. Unli ke the declination cabl[...]

focal lengths up to 1000mm and still enjoy a telescope that is relatively compact and portabl e. A Newtonian Reflector telescope offers such impressive light -gathering characteristics you can take a serious interest in deep space astronomy even on a modest budget. Newtonian Re flector telescopes do require m ore care and maintenance because the pr[...]

The celestial coordinate system has poles, lines of longitude and latitude, and an equat[...]

Latitude Scales The easiest way to polar align a telescope is with a latitude scale. Unlike other methods that require you to find the celesti al pole by identifying certain stars near it, this method works off of a known constant to determine how high the polar axis should be pointed (see figure 10). The constant, mentioned above, is a relationshi[...]
