Magnitudes
This menu item identifies up to ten celestial objects that lie within a range of about 10
degrees from where the telescope is currently pointing. Those objects nearest the central
axis are listed first, and the selection is refined as you designate the object’s catalog, type,
and maximum magnitude (These latter items appear in the menu tree as submenus of
each other).
You can scroll through the list of identified objects with the DEC buttons. As each object
is displayed, it becomes the "selected object," with coordinates and data available in the
information buffer. You now have two choices: (1) The RA+ button will immediately
GoTo the selected object; (2) the RA- button will display the information buffer and then
the object, ready for you to perform a GoTo.

5.3.8.1 Field of View Search
This feature is useful for systematically searching for objects that you know or suspect
are close to where the telescope is pointing, but are not in the field of view. After
selecting the “Object Search” menu item, you will be asked to select an FOV (field of
view) between 5 arcmin and 2 degrees, or select "Wobble Object."
