Nexstar SynScan instruction manual Identifying an Unknown Object, Recalling an user defined object

4.	The first available selection in the Object Catalog is Recall Object.	@D
	This is where you select previously-saved objects to view. Use the
	scroll keys to scroll down to "Input Coordi.>" and press ENTER.		l
5. The SynScanTMstores the user-defined objects in two formats-
	R.A/Dec and AltIAz. Press 1 for the R.A/Dec. format and 2 for the	Enter RA - DE C :
	Alt-Azimuth format.	2 2 h 4 6 . l m +90°00
6.	By default the SynScanTMwill display the R.A./Dec or AltIAz
	coordinates where the telescope is currently pointed. In the case
	of R.A/Dec format, the coordinate readout will be similar to this: "22h46.lmB+90~00"'

(Fig.m) which means 22 hours and 46.1 minutes in R.A. and "+90"00"' in Dec. 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 R.A./Dec coordinate entered does not exist, the SynScanM hand control will not respond when the ENTER key is pressed. Check the entry for inistake and re-enter the correct coordinatc.

7.To store an object/location in AltIAz format, first point the telescope to the desired location to obtain the AltIAz value, then press ENTER to save.

8.After the coordinates have been saved, the SynScan'" will display an User Object number as shown in Fig.n. Use the scroll keys to change to the number you wish to represent the coordinates and press ENTER.

9.The SynScanrMwill 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 may 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

1.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 SynScanr"hand control will display "Belo\w Horizon ! ! Try another obj ." and automatically return to the Recall Object menu.

Identifying an Unknown Object

SynScanrMhas the ability to identify the unknown object the telescope is currently pointing at. To do so, simply:

1.Press the ID key (Fig.0) 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.
