#1697 COMPUTER DRIVE SYSTEM : INTRODUCTION The Meade #1697 Computer Drive System (CDS) is easily installed in the Meade LXD 650 and 750 Equatorial Mounts.
- 5 - Basic T elescope Setup: 1. Polar align your telescope . See the instructions that accompany the telescope. 2. Turn "on" the #1697 Control Box. The Keypad Display (1), Fig. 6, displays “MEADE” for several seconds as the micro- processor does a self-diagnostic test.
- 6 - system’s computer memory . It is also necessary to learn the menu structure of the Keypad Hand Controller , which is described beginning on page 8. Basic CDS Setup: This section explains what keys to push to get the minimum data required into the computer system, without any detailed explanation.
- 7 - 2. Press the MODE key twice. The display will look like Display 8, but with random LOCAL and SIDE times. Display 12 9. Press and hold the ENTER key until the Keypad Hand Controller beeps. The display will look like Display 13, with the blinking cursor over the first number .
- 8 - Display 20 10 . Center the second alignment star in the telescope eyepiece using the "N", "E", "W", or "S" keys on the Keypad Hand Controller . Once the second star is centered, press the ENTER key to complete the alignment sequence.
- 9 - will show data on the object (name, rating, object type, brightness, and size). Now , press GO TO. The telescope will automatically slew to M42. If the desired object is not above the horizon, the Keypad Hand Controller will display the message “OBJECT BELOW HORIZON.
- 10 - THE CDS CONTROL P ANEL 1. Current (mA x 100) (1), Fig. 9: The Current (Ammeter) display is a series of vertical red LED bars. Each fully lit bar represents 1/10 of an amp (or 100 milliamps) of current draw , with the lowest value on the extreme left of the scale.
- 11 - information can be useful if you are trying to calculate how much battery life is available during an observing run. As an example, if the ammeter has four bars lit, (indicating 0.4 amps) and the system is using a 12 amp hour battery , determine the approximate battery life by dividing 12 amp hours by 0.
- 12 - pole star may be somewhat off-center in the eyepiece, showing that an alignment error was made during the initial setup. Using the Latitude adjustment knob and Azimuth control knob on the LXD Equatorial Mount, center the pole star during each interval exercise, then follow the rest of the routine.
- 13 - T o toggle between 12 and 24 hours displays, move the LCD arrow to 12/24HR and press ENTER. T o return to the original setting, press ENTER again. 5) HELP: The HELP menu selection of the TELESCOPE file is an electronic mini-manual that briefly describes the function of each command key on the CDS Keypad.
- 14 - and press ENTER. The letters will revert to lower case, indicating the High Precision Pointing option is now "off". 10) SLEW RA TE : Option #10 in the TELESCOPE menu is for changing the slew rate of the CDS telescope. Slowing down the slew rate will result in less noise as the telescope moves and will also use a little less power .
- 15 - using the M, ST AR, or CNGC keys, and pressing the ENTER key . Press MODE to exit to the main menu file. 2) ST ART FIND The ST ART FIND option utilizes the CNGC objects within the Object Library and begins a logical search beginning where ever the telescope is positioned when activated.
- 16 - selects all objects from very poor through super — what could be considered an “ALL” setting. The object quality symbols are: Quality Symbol Symbol Description SU Super EX Excellent VG V .
- 17 - the CDS knows no bounds — any celestial object, including comets, asteroids, etc., are easily found, provided accurate coordinate data has been entered. T o enter a new pointing position in Right Ascension and Declination, press and hold the GO T O key until a double beep is heard.
- 18 - Note: The backlighting is done by edge lighting a plastic light bar underneath the Keypad. Four LED’s are used and do not give a perfectly even backlighting of the keys as keys closer to a LED will be a little brighter than those keys further away .
- 19 - APPENDIX A: PRECISE POLAR ALIGNMENT Precise polar alignment is essential for long-exposure astrophotography (typically defined as photo-exposures of 10 minutes or longer). Fewer tracking corrections are required during the duration of the exposure when the telescope is precisely polar aligned.
