point the telescope to them for observing automatically. This is the “ Deep Sky Tour ” function.
Press the “ TOUR ” shortcut key. The screen will display “ Deep Sky Tour ” in the top row. User
can use the two scroll keys to browse through a list of the common names of the deep sky
objects and can press ENTER key to pick one of them.
• The screen will display the catalog to which the deep sky object belongs, as well as its
catalog index number in the top row. The object’s current azimuth and altitude will be
displayed in the bottom row.
• Use the scroll keys to browse the object’s J2000 celestial coordinates, magnitude
( MAG= ), rise time ( Rise: ), transit time ( Transit: ), set time ( Set: ), size ( size= ), and asso-
ciated constellation ( Constellation: ).
• Press ENTER key to proceed to the next step.
3. Locate the Object:
• The operation is similar to that of locating Messier objects; refer to Section 5.1 for de-

• If the “R.A.-Dec.” coordinates is chosen: The screen will display the coordinates to
which the telescope is pointing to at the moment.
• If the “Mount” coordinates is chosen: The screen will display the coordinates of the
mount’s two axes. The first number is the coordinates of the R.A. axis or azimuth axis,
while the second number is the coordinates of the Dec. axis or altitude axis.
