Align The Telescope - Vixen Starbook-S User Manual

Align the Telescope

(1) After moving the telescope to the home position, pressing the Select key will display the
western sky on screen in the northern hemisphere (the eastern sky in the southern hemisphere).
Tracking at sidereal rate starts at this time, but you should align the telescope to make the
tracking more accurate.
From among the celestial objects stored in the memory of the STARBOOK-S, at least two objects
must be selected as reference points to allow accurate automatic slewing and precise tracking of
celestial objects. Choose well-known bright stars to use as reference objects. Repeat this
procedure on at least two stars.
(2) SCOPE MODE and CHART MODE are alternated each time the Chart or GOTO key is
pressed.
The current MODE status is shown at the upper left of the screen. In SCOPEMODE, both the
screen and telescope move simultaneously with the keys. In CHART MODE, only the
screen is scrolled with the corresponding image of the sky. Always use CHART MODE when
searching for celestial objects on the screen. The two modes are linked to each other but
automatic slewing works from CHART MODE only. You cannot perform an alignment after
manually slewing in SCOPE MODE unless you first choose a target in CHART MODE.
