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 A d a p t e r.
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" 
L X 2 0 0 - A C F
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
