16" LX200GPS Unique Features
The 16" LX200GPS contains, for the most part, the same features (covered earlier in
this manual) as all other
LX200GPS telescope models. The following features are
unique to the 16" model.
Control Panel Features:
The Dec. Motor port (J, Fig. 43) is a DB-15 socket, designed to accept the supplied
coiled cord. One end of the coiled cord plugs into the power panel; the other plugs into
the Dec. Motor socket (Fig. 52) on the base of the fork arms to power the Dec. motor
and other electronic features.
The De-Rotater port (G, Fig. 43), for use in altazimuth alignment, allows you connect
the optional #1222 Field De-Rotater for long-exposure astrophotography by eliminat-
ing the image rotation inherent in altazimuth tracking. See
OPTIONAL ACCESSORIES,
page 43.
The "De-Rotater" menu option in the Utilities menu allows you to turn the De-rotater
on or off using the Autostar II handbox.
12 vDC Output (Fan) Port (E, Fig. 43) is used to power the fans located on the opti-
cal tube assembly (OTA). The fans evacuate the warm air trapped inside the tube,
allowing for faster cool-down.
The fan takes warm air from the OTA so that cool air can enter the OTA through the
filtered hole on the side of the OTA. The input filter prevents dust from entering the
OTA. Periodically replace the filter by removing the four bolts holding the grill. The fan
also has a filter, but this filter keeps dust out of the OTA while the fan is off; it should
not need replacing.
The "AUX Power" option in the Utilities menu allows you to turn the fan on or off.
Select "Yes" to turn on.
Commercial Shipping
Caution: Serious damage to the drive gears may result from shock in han-
dling. During transport or commercial shipping, the R.A. lock (12, Fig. 1)
and/or the Dec. lock (17, Fig. 1) must not be engaged. Always release the
locks when storing in the case or when crating for commercial shipment.
This allows the telescope to give if the case or crate is sharply jarred or
dropped.
The optical and mechanical axes of the 16"
LX200GPS telescope have
been carefully aligned at the factory to ensure accurate object pointing. Do
not loosen or remove the optical tube assembly from the tube adapters (25,
Fig 1).The resulting misalignment of the axes will result in inaccurate slew-
