LX200GPS: YOUR PERSONAL WINDOW TO THE UNIVERSE

The Meade LX200GPS models are extremely versatile, high-resolution telescopes. With pushbutton controls, precision GPS alignment, zero image-shift microfocusing, true-level and North electronic sensors, automatic tracking of celestial objects, peri- odic error correction for both axes, and a library of 125,000 objects in the Autostar II database, the LX200GPS models offer unmatched state-of-the-art performance.

Observe the feather structure of an eagle from 50 yards or study the rings of the plan- et Saturn from a distance of 800 million miles. Focus beyond the Solar System on ancient star clusters, remote galaxies, and stars recently discovered to have planets orbiting about them. Meade LX200GPS telescopes are capable of growing with your interest and can meet the requirements of the most demanding advanced observer.

BEyepiece: Place the Super Plössl 26mm eyepiece into the 90° diagonal prism (3, Fig. 1) and tighten in place with the eyepiece thumbscrew (2, Fig. 1). The eye- piece magnifies the image collected in the optical tube.

CEyepiece Thumbscrew: Tightens the eyepiece (1, Fig. 1) in place. Tighten to a firm feel only.

D1.25" Diagonal Prism (or 2" Mirror): Provides a more comfortable right angle view- ing position. A 2" diagonal mirror with a 1.25" adapter is standard with the 12" model. See page 14 for information about attaching the prism or mirror to the microfocuser.

EDiagonal Prism Thumbscrew: Tightens the diagonal prism in place. Tighten to a firm feel only.

FRear Cell Port: The microfocuser assembly threads onto this port.

GCoarse Manual Focus Knob: Moves the telescope’s primary mirror in a finely- controlled motion to achieve coarse image focus. The LX200GPS telescopes can be focused on objects from a distance of about 25 ft. to infinity. Rotate the focus knob counterclockwise to focus on distant objects, and clockwise to focus on nearby objects.

HFork Arms: This heavy-duty mount holds the optical tube securely in place.

IBattery Compartments: Insert four user-supplied C-cell batteries into each com- partment (one compartment on each fork arm; eight batteries total).

JPrimary Mirror Lock: Rotate this knob towards the "Lock" position and adjust the

tension to a firm feel; this action serves to lock in the coarse focus and also to pre- vent mirror flop. Use in conjunction with the Zero Image-Shift Microfocuser (see 2$).

1) Right Ascension (R.A.) Slow-Motion Control: Make fine adjustments in the Right Ascension, i.e., the horizontal axis, by turning this control with the R.A. Lock (see below) in the unlocked position. Set the R.A. Lock to a "partially locked" position to create a comfortable drag for the R.A. Slow Motion Control.

Caution: Do not operate the R.A. Slow Motion Control with the R.A. Lock in the fully locked position, as such operation may result in damage to the internal gear system and also cause you to lose alignment.

1! Right Ascension (R.A.) Setting Circle: See APPENDIX A, page 50, for detailed

information.

1@ Right Ascension (R.A.) Lock: Controls the manual horizontal rotation of the tel- escope. Turning the R.A. lock counterclockwise unlocks the telescope, enabling it to be freely rotated by hand about the horizontal axis. Turning the R.A. lock clockwise locks the telescope, prevents the telescope from being rotated manu- ally, and engages the horizontal motor drive for Autostar II operation.

1# Computer Control Panel (see Fig. 1 inset):

A. ON/OFF Switch: Turns the computer control panel and Autostar II ON or OFF. The red power indicator LED next to the switch illuminates when power is supplied to the Autostar II handbox, the microfocuser, and to the telescope’s motor drives.
