the cursor position and move to the next digit. If you want to skip a position and leave it unchanged use the East (E)
or West (W) keys to move the cursor. After the last digit is in place, pressing ENTER will cause Magellan to accept the
data as formatted.
4) Smaller
The SMALLER menu file option is the upper size object limit. At power up, the setting is for 200' arc minutes or 3.33°.
This setting is high enough to cover the largest objects in the OBJECT LIBRARY. You may want to lower the value
because of field-of-view limitations of a particular eyepiece.
Other reasons for limiting the value in SMALLER is for astrophotographic or CCD imaging requirements where you
don't want the object to exceed the imaging area of the film or the CCD chip. Setting values by using the keypad are
the same as previously described.
5) Brighter
The lower brightness limits based on stellar magnitude can be limited in the BRIGHTER menu file option. At power
up, the magnitude value is set to a very faint level of +20.0. You may want to adjust the magnitude level to a brighter
value starting at perhaps the limiting visual magnitude of your telescope. Sky conditions also greatly affect the limiting
magnitude due to atmospheric haze, high clouds, light pollution, or combinations thereof. Setting values by using the
keypad are the same as previously described.
6) Fainter
The upper level of brightness may also be adjusted with the FAINTER menu file option, although you may find few
applications for limiting it to a lower value. Setting values by using the keypad are the same as previously described.
e) User Library
This option allows the user to create a user library of 125 objects selected from the existing libraries. Pressing ENTER
will display the first of these 125 possible selections. Pressing PREV/NEXT will scroll through the user items. Press
ENTER to select a particular user item that you want changed or added. Pressing PREV/NEXT will move you through
the catalogs options, press ENTER when you have the object library you wish to choose from. You may then enter the
object number with the keypad as in previous menus followed by ENTER to complete the selection.
2. Align
Alignment of your telescope is the most critical procedure for the successful use of Magellan. The alignment
procedure allows Magellan to determine the orientation and position of the telescope, and to thereafter guide you
accurately to objects in the sky. The alignment function is selected from the menu by pressing ENTER when "Align" is
indicated by the display arrow.
Next to the word "Align" on the Magellan display there is a number ("0" after power is applied). This number
represents the quality of the alignment procedure performed. It is derived from taking the measured alignment values
and comparing them with what should be expected based on the distances between the alignment objects. A value of
100 (as in 100%) means that your actual alignment measurements matched those expected based on calculations.
Values between 90 and 110 are accepted but may affect pointing accuracy when moving to other objects. Values out
of this range are not acceptable and will require that you make another attempt to align your telescope. The initial
value of "0" indicates that Magellan is not aligned.
a) Polar Alignment
Polar alignment is the only alignment offered for Magellan II. Position the telescope/mount system such that it is
aligned with the pole (the pole is in the center of the field of view and the telescope is at 90°( Declination). Your
telescope instruction manual will provide information on this initial telescope positioning. Once in position, press
ENTER as requested by the display.
