Identifying an Unknown 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	@D
	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.

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.

SynScan specifications

The Nexstar SynScan is a highly regarded mount and telescope system, catering to both amateur astronomers and seasoned professionals alike. Renowned for its ease of use, portability, and advanced technology, it significantly enhances the stargazing experience.

One of the standout features of the Nexstar SynScan is its computerized GoTo mount. This system allows users to easily locate and track celestial objects. With an extensive database of over 40,000 celestial bodies, including stars, planets, nebulae, and galaxies, the SynScan offers an intuitive way to explore the night sky. The built-in database also includes user-defined objects, making it versatile for personalized astronomical pursuits.

The SynScan's Dual-Axis Tracking mechanism is another major advantage. It accurately tracks celestial objects as they move across the sky due to the Earth's rotation, ensuring that users can view objects for extended periods without needing to manually adjust the telescope. This functionality is particularly beneficial for astrophotography, as it reduces image blurring caused by slight movements.

In terms of technology, the Nexstar SynScan utilizes a precision motor drive and encoders to enhance tracking accuracy. The mount features AC servo motors, which provide smooth and silent operation. The included hand control is user-friendly, with a backlit screen that allows for night-time navigation without disturbing your surroundings.

The system's ease of setup and portability are important characteristics, particularly for users who wish to observe in remote locations. The Nexstar mount is lightweight and compact, making it easy to transport and assemble. Users can quickly set up the telescope in a matter of minutes, an advantage for spontaneous night-sky explorers.

Additionally, the SynScan offers various power options, including the ability to use AA batteries or an external power supply. This flexibility ensures that users can operate their telescope in different environments without worrying about finding power sources.

Lastly, the Nexstar SynScan is compatible with popular astronomy software, enabling users to enhance their observing sessions with additional features such as software-guided observations and advanced tracking capabilities. This integration with technology allows for a rich observing experience where the vastness of the universe is made more accessible.

In conclusion, the Nexstar SynScan stands out for its combination of advanced technology, user-friendliness, and portability, making it a top choice for anyone looking to delve deeper into the wonders of astronomy.
