Anleitung Zusammenfassung
5. The stores the user-defined objects in two and Press 1 for the format and 2 for the 6. By default the will display the or coordinates where the telescope is currently pointed. In the case of format, the coordinate readout will be similar to this: which means 22 hours and 46.1 minutes in R.A. and in Change the coordinates using the numeric keypad and scroll keys. Use the RIGHT or LEFT directional keys to move the cursor to the next or previous digit. Press ENTER to save. If the coordinate entered does not exist, the SynScanM hand control will not respond when the ENTER key is pressed. Check the entry for and re-enter the correct coordinatc. 7. To store an format, first point the telescope to the desired location to obtain the value, then press ENTER to save. 8. After the coordinates have been saved, the will display an User Object number as shown in Use the scroll keys to change to the number you wish to represent the coordinates and press ENTER. 9. The will display "View Object?" and the User Object number you just entered. Press ENTER to go to the object or ESC to return to the lnput Coordinate menu. The User Object number displayed not be a vacant one. If you are unsure which numbers are vacant, it is recommended that you first check for the available numbers by recalling the saved user objects. Recalling an user defined object See Step 1-4 of "Saving an object to the database" for details on how to access to the User Defined menu. Select Recall Object and press ENTER. 2. Use the scroll keys to browse through the User Object number until the number representing the object you wish to view is present. Press ENTER to show its coordinate. Press ENTER again to slew to the object. The hand control will not respond if a vacant User Object number is selected. Use the scroll keys to choose another number and try again. If the recalled object is below horizon, the hand control will display ! Try another obj and automatically return to the Recall Object menu. Identifying an Unknown Object has the ability to identify the unknown object the telescope is currently pointing at. To do so, simply: Press the ID key or scroll down to IDENTIFY in the main menu and press ENTER to identify the object. 2. The hand control will display a list containing the closest known object in each M, IC, NGC, and Named Star catalogs and its distance to the exact location where the telescope is pointed. Use the scroll keys to view these objects. 3. Press ESC to exit from this function. - in with A Computer Another feature of is the ability to connect to a computer via a serial communication cable. Many commercially available planetarium softwares can be used to control Version 3.00 and later is compatible with Celestron and NexStar GPS command protocol. 1. Make sure that the telescope has been aligned. Hand Control 2. Connect the RS-232 cable to the RJ-11 connector on the hand control and to the COM-port of your computer Do not use RS-232 cable other than the one provided to connect between the hand control and your computer. It RJ- 11 may damage your computer or the hand control. If you are making your own cable based on the information provided in Appendix B, make sure that only pin 2, 3 and 5 connect to the connector on your computer. 3. In the planetarium software of your choice, choose "Celestron NexStar or "Celestron 8/9/11 GPS" in the driver setup menu and follow the instructions provided by your program to establish the connection to the telescope. The should be under the full control of your RJ-11 Pin-outs GND EXPDRD 654321 See Appendix B for computer once the connection is successfully established. 4. When you are finished, follow the instructions provided by RS-232 connection. your software to close the connection to the telescope. Auto Guiding The has a designated autoguider interface on the mount for use with NC an auto guider (see a-I). The pin-outs on the 6 pin modular connector is Ground ST-4 compatible and can be used for most autoguiders on the market. Refer to (left) when (up) (down) the autoguider cable to the SynScanTM and calibrating the autoguider. Relay box can be added for extra protection. Note that the four inputs are active-low, with internal pull-ups. Guiding speed can be adjusted using the -RA (right) Auto Guide Speed function in the Setup Menu. Periodic Error Correction Periodic Errors are found in almost all worm gears due to slight eccentricities and misalignments. The PEC (Periodic Error Correction) function provides a manual correcting method to reduce the amplitude of the worm errors. By recording a full cycle of guiding actions versus motor shaft angle, work to compensate for the drifting in the RA sidereal tracking caused by the periodic errors. Below describes a step-by-step procedure on how to perform the PEC: PEC Training function is recommended for advanced users interested in long-exposure astrophotograhy only. Careful guiding is required. Regular sidereal tracking is adequate for all casual vis...
