Pressing this key while in the object find mode will cause the telescope to slew at 32x speed to the object selected.
This key is only active when the object is within 2° of the present telescope position. The intention of this function is to
make the final adjustment to telescope position after the larger moves have been done manually.
4. Direction (N, S, E, W)
Pressing these keys will cause the telescope to slew in the direction selected at the speed indicated by the speed
LED's on the right side of the handbox. These keys are also used in some editing functions to move the cursor to a
particular character in a sequence without changing characters skipped.
5. Numeric and Function
These 10 keys have dual purposes based on the mode of the Magellan handbox. For modes where data is being
entered, like selection of a catalog object number, these keys are used for numeric input as indicated by the number
on the key. Pressing the numeric key will enter the number into the character indicated by the cursor and move to the
next logical character in the sequence. After the last number is entered, the ENTER key is pressed indicating the
acceptance of the input as a whole.
When not in an editing mode these keys are assigned certain specific functions, keys 0, 1, 4 and 7 are used to
change the slew rate of the telescope. They are marked with a speed value from 2x to 32x and when pressed will alter
the subsequent telescope slew rates as selected by the user. Pressing these keys will also alter the speed display
LED's associated with each key along the right side of the handbox.
Keys 2, 3, 5, 6 and 9 are used as catalog selection keys when not in an editing mode. The CNGC Catalog can be
selected by pressing the CNGC key (3). The Star Catalog and Planets can be selected by pressing the STAR key (6).
The Messier Object Catalog is selected using the M key (9). The IC Catalog is selected by pressing the 2 key. The
User Catalog is selected by pressing the 5 key.
6. Prev and Next
Pressing the PREV key moves the display LCD arrow up the list of menu items, while pressing the NEXT key moves
the display LCD arrow down the list of menu items. In the BRIGHTNESS mode, these keys adjust the intensity of the
LCD and keypad backlighting.
C. Communication Ports
Communication ports are found on the bottom of the handbox case. These ports are designed to accept cables using
the standard high reliability telephone technology plugs. A positive snap action design prevents the cable from
disconnecting during usage.
1. Telescope Port
The telescope port accepts a 4-pin plug from the telescope control panel. This coiled cable carries two signals and
power to the Magellan Handbox from the telescope. This connector should only be connected or disconnected while
the telescope power is off.
2. RS-232 Port
The RS-232 port is used to connect a personal computer to the Magellan System for added features. Magellan
communicates telescope position information via this interface to software like Epoch 2000, which can then display
star maps of the telescope field of view and perform other helpful functions.
IV Operations
Magellan operates under one of four modes that are cycled by pressing the MODE key. The four modes are,
