APPENDIX F: 16" LX200-ACF FEATURES 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. Figure 45: 16" LX200-ACF Computer Control Panel. 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. - 65 -
