Identify
Identify Mode will search any of the mount'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 that Epsilon Lyrae is only 1°
away from Vega To use the Identify feature:
• Press the Menu button and select the Identify option
• Use the Up/Down scroll keys to select the catalog
that you would like to search
• Press ENTER to begin the search
NOTE: Some of the databases contain thousands of
objects and can therefore take several minutes to return the
closest objects.
Precise GoTo
The mount has 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 astroimaging Precise
GoTo automatically searches out the closest bright star to
the desired object and asks the user to carefully center the
star in the eyepiece The hand control then calculates the
small difference between its GoTo position and its centered
position Using this offset, the mount will then slew to the
desired object with enhanced accuracy
To use Precise GoTo:
1 Press the MENU button and use the Up/Down keys
to select Precise GoTo
• Choose Database to select the object that you want
to observe from any of the database catalogs listed or;
• Choose R A /DEC to enter a set of celestial coordinates
that you wish to slew to
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
3 Use the direction buttons to carefully center the alignment
star in the eyepiece
4 Press ENTER to slew to the desired object
