The setting circles, R.A 10, Fig. 3 and Dec. 3, Fig. 3 of the LX200 7, 8, 10, and 12 telescopes may be dialed, in effect, to read the object coordinates and the object found without resorting to visual location techniques. However, these setting circles may be used to advantage only if the telescope is first properly aligned with the North Celestial Pole toc 2. Lining Up with the Celestial Pole toc 3.

Left unattended, it can cause damaging corrosion. To keep dust at bay when observing, the telescope can be set up on a small section of indoor/ outdoor carpet. If you are observing for more than one night in a row, the telescope can be left set up but covered with a large plastic bag such as the one supplied with the telescope. The rear cell opening of the LX200 can also be sealed off to the elements by threading on the optional accessory Skylight 1 A Dust Seal*. Eyepieces, diagonals, and other accessories are best kept in plastic bags and stored in cases, such as the Meade #50 Accessory case Page Page Fig. 27: Defocused Star Images toc 4.
