Hint
Identify
Identify Mode will search any of the telescope's database catalogs or lists and display
the name and offset distances to the nearest matching objects. This feature can serve
two purposes. First, it can be used to identify an unknown object in the field of view
of your eyepiece. Additionally, Identify Mode can be used to find other celestial
objects that are close to the objects you are currently observing. For example, if your
telescope is pointed at the brightest star in the constellation Lyra, choosing Identify
and then searching the Named Star catalog will no doubt return the star Vega as the
star you are observing. However, by selecting Identify and searching by the Named
Object or Messier catalogs, the hand control will let you know that the Ring Nebula
(M57) is approximately 6° from your current position. Searching the Double Star
catalog will reveal th

P
recise GoTo
The CGE Series telescopes have a precise goto function that can assist in finding
extremely faint objects and centering objects closer to the center of the field of view
for astrophotography and CCD imaging. Precise Goto automatically searches out
the closest bright star to the desired object and asks the user to carefully center it in
the eyepiece. The hand control then calculates the small difference between its goto
position and its centered position. Using this offset, the telescope will th
th
e desired object with enhanced accuracy. To use Precise Goto:
1.
Press the MENU button and use the Up/Down keys to select Precise Goto.

2. Once the desired object is selected, the hand control will search out and display the closest bright star
to your desired object. Press ENTER to slew to the bright alignment star.
