16" LX200-ACF Unique Features
The 16" LX200-ACF contains, for the most part, the same features (covered earlier in
this manual) as all other LX200-ACF telescope models. The following features are
unique to the 16" model.
Control Panel Features:
18vDC Power Connector (Fig. 45, B): Provides a connection so that the telescope
assembly may be powered from a standard 115v AC home outlet using the supplied
Power Adapter.
The De-rotator port (Fig. 45, G), for use in altazimuth alignment, allows you connect
the optional #1222 Field De-rotator for long-exposure astrophotography by eliminating
the image rotation inherent in altazimuth tracking. See
OPTIONAL ACCESSORIES,
page 44.
The “De-rotator” menu option in the Utilities menu allows you to turn the De-rotator on
or off using the AutoStar II handbox.
12 vDC Output (Fan) Port (Fig. 45, E) is used to power the fans located on the optical
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
handling. During transport or commercial shipping, the R.A. lock
(Pg. 7, Fig. 1, 12) and/or the Dec. lock (Fig. 1, 17) 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"
LX200-ACF
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 (Fig
1, 25). The resulting misalignment of the axes will result in inaccurate
slewing of the telescope in the GO TO mode. Do not attempt to turn the
focus knob of the optical tube (Fig. 1, 6) until you have read the following
note.
Caution:
Due to the weight and size
of the 14" and the 16"
LX200-ACF
models, please
use extreme caution
whenever assembling,
disassembling, lifting,
transporting or storing this
product. Two or more
persons should always be
used whenever performing
any of the above tasks.
Disregard for the above
warning could result in
serious injury or death.
