Once the telescope has been aligned. You can now access and view the 13,400 different objects 
in the EQ6 SkyScan

TM

 database. There are three methods of selecting a celestial object to view:

TOUR

 - Takes you on a preset tour across your current sky. It 

will automatically choose from the database the brightest and 
most beautiful deep-sky objects for your viewing pleasure. Use 
the down scroll key to view through the deep sky objects. 
Choose the desired object by pressing 

ENTER. 

It will show the 

coordinate of the chosen object. Pressing 

ENTER

 once more will 

cause the telescope to slew to the object.

M, NGC, IC

 - These shortcut keys give you access to the most 

popular celestial catalogues to date. Each Catalogue has a set 
number of objects to choose from. Use the numeric keys to 
select an object by entering its number. Pressing 

ENTER

 will 

display its coordinate. Primary information such as size, 
magnitude, and constellation are obtained by pressing the scroll 
keys. Pressing 

ENTER

 once more will cause the telescope to 

slew to the object.

PLANET

 - This shortcut key takes you straight to the Planets 

sub menu in the database. Use the scroll keys to scroll through 
the list of planets in our solar system. Press 

ENTER

 to view its 

coordinates, and 

ENTER

 once more to slew to the planet.

USER

 - This will take you to the database that you have defined 

for yourself. You can enter a new location or recall the objects 
that have been previously saved (see Using the User Defined 
Database).

The 

OBJECT

 key takes you to the Objects Catalogue, where 

you have complete access to over 13,400 celestial objects in the 
database. (See Object database in the 

EQ6 SkyScan

TM

 and the

and 

press 

ENTER

. Similar to the
