Overview: 64,359 Object Library The CDS 64,359-Object Library is a collection of the most studied and fantastic objects in the sky. This library consists of the following object databases: • • • • • • • • 110 Messier objects. 351 bright stars, interesting double stars and Sigma Octans (the southern star) in the star . 15,928 SAO (Smithsonian Astrophysical Observatory) Catalog of Stars: all stars brighter than 7th magnitude. 21,815 GCVS (General Catalog of Variable Stars) objects: complete catalog. 7,840 NGC (New General Catalog*) objects: complete catalog. 5,386 IC (Index Catalog*) objects: complete catalog. 12,921 UGC (Uppsala General Catalog) galaxies: complete catalog. 8 Major Planets and the Moon. 2. Accessing the Object Databases A. Messier Catalog: 1. Press the M key. 2. Enter the number of the desired Messier object and press ENTER. 3. Object information will appear on the display. B. Planets and Moon: The CDS calculates the orbital positions of the Moon and the eight major planets for the current calendar date. To access the Moon or a planet, press the STAR key and enter the appropriate number as indicated below: OBJECT LIBRARY PLANET LEGEND PLANET MERCURY STAR # 901 VENUS MOON MARS JUPITER SATURN URANUS NEPTUNE PLUTO 902 903 904 905 906 907 908 909 C. Star, SAO and GCVS Catalogs: 1. Press the STAR key on the Hand Controller, then press ENTER. 2. Use the PREV and NEXT keys to cycle through the following options: NAME STAR SAO GCVS Alphebetical listing of 33 bright alignment stars. 250 brightest stars, 100 interesting double stars and Sigma Octans (the southern hemisphere). The list of stars begins on page 27. The Smithsonian Astrophysical Observatory catalog of stars (all stars brighter than 7th magnitude). The General Catalog of Variable Stars (complete catalog). Variable stars from the GCVS are entered using a six digit number. The first two digits, refer to the constellation where the variable star is located and is listed in the table below. The next four digits are assigned sequentially within each constellation according to the standard sequence of variable-star designations (R, S, ...). Therefore, the first variable star in the constellation of Virgo would be entered as: 860001. 3. Press Enter when the desired catalog is selected. An arrow will appear to the right of the selected catalog. 4. Press MODE to activate the curser. Using the keypad, enter the number of the desired selection into the Hand Controler and press ENTER. The object information of the selected object then appears on the screen. * NGC 2000 and IC databases are copyrighted by Sky Publishing Corporation and used with their permission. - 24 - D. CNGC, IC, and UGC catalogs: 1. Press the CNGC key on the Hand Controller, then press ENTER. 2. Use the PREV and NEXT keys to cycle through the following options: NGC IC UGC New General Catalog (complete catalog). Index Catalog (complete catalog). Uppsala General Catalog (complete catalog). 3. Press Enter when the desired catalog is selected. An arrow will appear to the right of the selected catalog. 4. Press MODE to activate the curser. Using the keypad, enter the number of the desired selection into the Hand Controler and press ENTER. The object information of the selected object then appears on the screen. The CDS “remembers” the database you last accessed. Each time you press the CNGC key, the same object database will be displayed on the first line of the Keypad display. To change databases, press ENTER to bring up the database menu. 3. The Meade CNGC* Catalog You will notice that the Messier (M) objects, and the NGC objects have been incorporated into the Meade Instruments CNGC listing. CNGC stands for “Computerized New General Catalog of Non-Stellar Astronomical Objects”. The CNGC is an enhancement from the RNGC (Revised New General Catalog) in many ways. Angular sizes are given in arc-seconds on the CNGC listing, and in a convenient scaled format on the CDS Keypad Display. The complete CNGC contains 7,840 objects, most of which appear in the RNGC (Revised New General Catalog) with the same number. More than 400 objects were added to the RNGC to create the CNGC. Most of these “should have been” in the RNGC in the sense that they are bright and large enough to have been included. The CNGC is enhanced from the RNGC in many ways. Angular sizes are given in arc-seconds on the CNGC listing, and in a convenient scaled format on the CDS display. Magnitudes are given to 0.1 magnitude where possible. The coordinates in the CNGC listing are listed for the year 2000. The CDS calculates object positions upon power up to the current date (as shown on the time/date display). This makes the CDS pointing more accurate. Therefore, the CNGC listing and the CDS display will not exactly agree on object positions. Objects have been assigned a “Visual Quality Rating”, henceforth called VQ. A large number of VQs have been obtained by direct visual observations the objects. To make the VQs as useful as possible, all observations have been made with the same telescope and eyepiece under essentially identical observing conditions. A higher power eyepiece was used only for very small objects. Your “Visual Quality Rating” of a particular object will vary, largely due to sky conditions. If the object has been rated by observation, an upper-case character (ABCDEFG) is used for the VQ on the CNGC listing. If the object has not been observed, the VQ has been estimated by a computer program from the object type, size, and brightness and the VQ is specified in lower-case characters (abcdefg). The VQs for visually-rated objects are a considerably more consistent guide to observability and appearance than either the computed VQs or an examination of the type, magnitude, and size data. All, or very nearly all, of the objects in the CNGC are visible with the standard instrumentation and observing conditions used to obtain the visual quality ratings. It is a good indication of what can be expected with similar equipment by experienced deep-sky observers in excellent sky conditions. Naturally smaller telescopes and/or less optimal observing conditions will lower the apparent quality of all objects. * The Meade CNGC Catalog is copyright by Meade Instruments Corporation. - 25 - The following guide to VQs was used in the visual observing process. SUPER Very bright object with very interesting shape or structure. EXCEL Bright object with very interesting shape or structure. OR Very bright object with moderately interesting shape or structure. V GOOD Bright object with moderately interesting shape or structure. OR Very bright object with little or no interesting shape or structure. GOOD Easy to see without averted vision with some interesting shape or structure. OR Bright object, but little or no interesting shape or structure. FAIR Easy to see without averted vision, but little or no interesting shape or structure. POOR Easy to see with averted vision. Often borderline visible without averted vision. V POOR A struggle to see with careful use of averted vision. (none) Not yet rated AND missing information for computer estimate. OR Could not see despite careful use of averted vision. The following is a description of the format of the optional CNGC listing for each object: COLUMN NAME DESCRIPTION 1 CNGC # 2 RA 3 DEC Declination 4 SIZE Size of object (arc-seconds) 5 MAG Magnitude (-5.5 through 19.9) 6 TYPE Type of object 7 * * means object is not in the RNGC 8 ALT CAT Alternate catalog name and number 9 VQ 10 TAGS 11 COMMENTS CNGC 0001 through CNGC 7840 Right Ascension Visual Quality Rating (abcdefg ) or (ABCDEFG) Object Type # (0-F) : S = Sky-Cat : T = Tirion Name, comments, other information - 26 - The following types are distinguished in the CNGC.

36 - APPENDIX D: PERSONAL COMPUTER (PC) CONTROL OF THE #1697 CDS Remote operation of a computerized telescope has only been a fanciful dream for most amateur astronomers. The realization of fully controlling a telescope through a personal computer has previously been a staggering proposition involving high monetary cost and expert knowledge of software and hardware. To realize this dream, the Meade #1697 Computer Drive System's internal software supports a RS-232 interface, allowing observers to utilize a PC and software such as Meade EPOCH 2000sk (see Optional Accessories, page, 18), other after-market software, or a user's own custom software to control a compatible telescope. The following sections are devoted to those interested in developing their own software to remotely control every feature of the CDS. An RS-232 cable is required for serial communication between the CDS and a PC. It Fig. 14: EPOCH 2000sk. is possible to either purchase an RS-232 cable from your local Meade dealer, or construct your own cable. Following is a schematic for constructing your own RS-232 cable, a program to test the RS-232 communication line called CDS TEST, the CDS Command Set, and CDS DEMO, which is a program that you can enter into your computer to access the Object Library, slew to the object, and center the image. The CDS TEST and CDS DEMO programs require a serial communication program, such as Procomm*, to communicate with a PC. 1. RS-232 Cable The input hardware uses a standard 6 line telephone jack connector, preattached to a 6 conductor flat line telephone style cable (of any length, up to 100' and perhaps even more, depending on the gauge of the cable). You will also need either a 9-pin or 25-pin RS-232 connector, whichever your computer uses for the serial port. All of the above items are available at most electronics hardware stores. 142 536 Fig. 15 shows the CDS pinouts for the 6 line telephone connector. The table below shows standard IBM compatible DB-9 and DB-25 serial port pin outs, and how they should be connected to the CDS 6 line modular connector. Note: Only 3 wires are required. 6 1 4 2 5 3 Fig. 15: CDS Modular Connector RS-232 CONNECTOR PIN OUT CODE LEGEND * ** 6 WIRE MODULAR CONNECTOR DESCRIPTION TO DB-9 CONNECTOR PIN#** TO DB-25 CONNECTOR PIN#** #1 +12 VOLTS DC NOT USED NOT USED #2 MISC.

The DB-9 and DB-25 serial port pin out numbering code is representative of a widely used standard format. Consult your computer’s instruction manual for your computer's format. - 37 - 2. CDS Test Program Once you have the RS-232 cable constructed, you will want to test the cable. Below is a simple program called "CDS TEST” that is written in GW Basic programming language and will work with virtually any IBM compatible computer. CDS Test is an effective program to fully check the RS-232 line communications from your personal computer to the CDS, allowing you to concentrate on de-bugging your RS-232 cable. To enter the following program, first load BASIC or GWBASIC (which ever your computer system uses), then type in the following program. When complete, be sure to save the program as “CDSTST.BAS.” 10 CLS 20 DEFINT A-X 30 OPEN "COM1:9600,N,8,1,CD0,CS0,DS0,RS," FOR RANDOM AS #1 50 key1$ = INKEY$: IF key1$ = "" THEN GOTO 50 60 REM KEY1S 70 IF key1$ = CHR$(119) THEN GOSUB 200: REM "w" key 80 IF key1$ = CHR$(101) THEN GOSUB 200: REM "e" key 90 IF key1$ = CHR$(110) THEN GOSUB 200: REM "n" key 100 IF key1$ = CHR$(115) THEN GOSUB 200: REM "s" key 105 IF key1$ = "x" THEN END: REM To exit test. 110 GOTO 50 120 END 200 REM directions 210 REM west 220 IF key1$ = "w" THEN a$ = "#:Mw#": PRINT #1, a$: REM GO 230 REM east 240 IF key1$ = "e" THEN a$ = "#:Me#": PRINT #1, a$: REM GO 250 REM north 260 IF key1$ = "n" THEN a$ = "#:Mn#": PRINT #1, a$: REM GO 270 REM south: 280 IF key1$ = "s" THEN a$ = "#:Ms#": PRINT #1, a$: REM GO 290 key1$ = INKEY$: 300 IF key1$ = CHR$(32) THEN GOTO 400 ELSE GOTO 200 400 REM This stops motion (by hitting SPACE bar). 410 B$ = "#:Qe#": PRINT #1, B$ 420 B$ = "#:Qw#": PRINT #1, B$ 430 B$ = "#:Qn#": PRINT #1, B$ 440 B$ = "#:Qs#": PRINT #1, B$ 450 RETURN 460 END west east north south To use the above program, connect the completed cable to your PC serial port and to the CDS RS-232 Port. Load BASIC (or GWBASIC), if not already loaded, and run “CDSTST.BAS.” Nothing will appear on the computer screen. Press any one of the N, S, E, or W (lower case) keys on your PC keyboard, this will move the LXD mount North, South, East, or West respectively. Press the space bar on the PC keyboard to stop. Press X to exit the program. If the LXD mount does not respond to the N, S, E, or W keys, be sure the CAPSLOCK is OFF. If it still does not work, check the PC serial port pinouts for your computer to be sure they are wired correctly to the CDS 6 line connector. With a successful check-out of the PC link with the CDS using “TEST”, you are now ready to write your own software program using the CDS Command Set, or to use the sample program called “DEMO” that is written in Quick Basic software language. - 38 - 3. CDS Command Set Intended for professional programmers, the CDS Command Set is used to write custom software for remote operation of the telescope with a PC. Each command is listed in a section appropriate to its type. Each entry in the command list includes the command name, any parameters, any return values, and a description. The parameters and the return data are shown in a manner that indicates their format. These formats are listed below along with examples of how the data might really appear, the legal range of values, and a short description. Below is a detailed description: a.

CDS Demo Program The RS-232 interface communicates with your computer at 9600 Baud Rate, Parity = None, 8 Data Bits, 1 Stop Bits. For those who are familiar with programming, the CDS Command Set is written in ASCII character format and can be used to write your own programs. The CDS Demo Program is written in Quick Basic and is intended to demonstrate how commands can be sent to the telescope and information received from the telescope. It is not a “polished” program and does not incorporate all of the RS-232 features available. The program is set-up to operate on serial port 2 (COM2:). To operate on serial port 1 (COM1:) line 4 should be changed from “COM2:” to “COM1:”. The program is as follows: Please note that Meade Instruments does not support these programs, or programs that you may write in any way. For questions relating to after-market software programs, refer back to those manufacturers. - 45 - CLS DEFINT A-X counter = 0 OPEN "COM1:9600,N,8,1,CD0,CS0,DS0,OP0,RS,TB2048,RB2048" FOR RANDOM AS #1 hourform$ = "low " KEY ON KEY(1) ON KEY 1, "GO TO": ON KEY(1) GOSUB key1 KEY(2) ON KEY 2, " SYNC" ON KEY(2) GOSUB KEY2 KEY(3) ON KEY 3, " SLEW" ON KEY(3) GOSUB key3 KEY(4) ON KEY 4, " FIND" ON KEY(4) GOSUB KEY4 KEY(5) ON KEY 5, " CNTR" ON KEY(5) GOSUB KEY5 KEY(6) ON KEY 6, "GUIDE" ON KEY(6) GOSUB KEY6 KEY(7) ON KEY 7, " H.P."

Keeping Your Components Clean Prevention is the best recommendation that a telescope owner can follow in keeping astronomical equipment in top working order. Proper measures taken during observations and when storing the equipment between observation runs can ensure many years of trouble free use. Dust and moisture are the two main enemies to your telescope and electronics. If you live in a very moist climate, you may find it necessary to use a silica dessicant stored with the telescope and electronics to ward off moisture and the possibility of corrosion growing on the metal contacts of the electronics. Replace the silica dessicant as often as necessary. All of the metal surfaces should be cleaned routinely with a soft rag and alcohol to prevent corrosion. Those living in coastal areas or tropic zones should also cover the electronic ports on the Control Panel and Keypad with gaffers tape to reduce corrosion on the metal contacts. Apply a dab of water displacement solution (such as WD-40) with a small brush on all of the interior metal contacts and the input cord metal contacts. The Keypad and all separate accessories should be kept in sealable bags with silica dessicant. 2. Behind the Power Panel The CDS Control Panel houses the back-up replaceable clock/ calendar battery and a replaceable standard 1.0 amp slow blow fuse. The long-life lithium battery (Panasonic CR2032 3 volt or Duracell DL2032B) is stored behind the front panel of the CDS. The battery should be replaced whenever the CDS begins to lose time. The 1 amp slow blow fuse will fail in the event that the telescope is prevented from completing a GO TO function (e.g. the tube runs into something that keeps it from slewing). To replace either the battery or the fuse, first remove the CDS PCB assembly from the Declination casting by removing the four screws and unplugging the 16-pin ribbon cable. With a thin flat-headed screwdriver, lift the small coin-sized battery out of its’ holder. The new battery slides back in place. 1 Fig. 16. CDS PCD. (1) 16-Pin Ribbon Cable. The fuse can be removed with the aid of a small screwdriver. Loosening the two upper screws on the front side of the power panel will provide more clearance to replace the fuse if needed.
