1.First, determine the Magnetic Declination in your area using the Isogonic Chart (Fig. 15)

2.Squeeze the clear central vial with thumb and index finger of the left hand.

3.With the right hand, rotate the outer dial until the orienting arrow (the black arrow painted on the inside clear surface) is lined up with the desired Magnetic Declination angle on the declination scale. Notice that East Magnetic Declination is to the right of the "North" position and West Magnetic Declination is left of the "North" position. As an example, Fig. 16. shows the correct setting for 16 degrees West Declination, which covers Providence, Rhode Island.

The Magnetic Compass is now set for the correct

declination angle. To attach to the Equatorial Wedge, follow these steps:

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 3.
