What About Power?
To calculate power, divide the focal length of the telescope
(e.g., 700mm for Model NG-70) by the focal length of the
eyepiece (e.g., 25mm).
Lower power eyepieces (e.g., 25mm) offer wide fields of view
for observing deep-space and terrestrial objects. Higher
power eyepieces (e.g., 9mm) offer greater magnification and
are useful for observing surface detail on the Moon and
planets.
The Importance of Computerized Tracking
and Object-Location
Observing an astronomical object involves following a
constantly moving target. Every object in the sky moves in
the same manner as our Sun, rising in the East and setting in
the West. This apparent celestial movement is caused by the
rotation of the Earth.
Computerized Tracking: To the unaided eye an object
like the Moon appears to move slowly across the sky, but
will, in fact, move surprisingly quickly through the field
of view of a telescope. The AutoStar® Computer Control
System directs the telescope to automatically follow fast-
moving celestial objects.
Automatic object-location: A novice astronomer often
spends a disproportionate amount of time learning the
sky and searching for subjects to view. AutoStar
technology obliterates this learning curve. Meade's
revolutionary AutoStar Computer Control System
facilitates automatic object-location and tracking of over
1400 objects.
