APPENDIX A: EQUATORIAL WEDGE

IMPORTANT NOTICE! Never use a telescope or spotting scope to look at the Sun!

Observing the Sun, even for the shortest fraction of a

second, will cause irreversible damage to your eye as well as physical damage to the telescope or spotting scope itself.

APPENDIX A: EQUATORIAL WEDGE

There are two equatorial wedges used on Meade LX200 telescopes.

Please read the section, below, that applies to your telescope.

[ toc ] 1. 8" Equatorial Wedge (For 7" and 8" LX200)

The Equatorial Wedge permits use of the 8" LX200 telescope in an astronomical, or "equatorial," mode. The wedge fits onto the field tripod, described below, and accepts the base of the 7" or 8" LX200 fork mount. See Fig. 8.

NOTE: The Meade equatorial wedge is designed solely for use in conjunction with the Meade field tripod. The wedge should never be used without the field tripod, e.g. by placing the wedge alone on a table top and then mounting the telescope on the wedge. The 7" or 8" LX200, placed onto the equatorial wedge alone without the field tripod attached to the wedge may become seriously imbalanced, to the point where the telescope may actually tip over.

The equatorial wedge for the 7" and 8" LX200 telescope is of modern design, with several important features incorporated to simplify and facilitate telescope operation. After using the wedge, you will find that the functional design features included are of very significant value in routine telescope operations. Features included are:

1.Attachment of the wedge to the field tripod by means of only one manual knob.

2.Quick azimuth adjustment by loosening the manual knob as described above.

3.Bubble level for rapid tripod/wedge leveling.

4.Etched latitude scale for fast adjustment of the latitude angle.

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.

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.
