3. The hand control will generate a list of the bright stars within the selected horizontal region.
The list is sorted by the brightness of the star, with the brightest stars at the top of the list.
Users can use the scroll keys to browse the list. An example of the screen display is shown
in Fig. 3.4b.
• Only stars brighter than magnitude 1.5 will appear in the list. If there are no stars bright-
er than magnitude 1.5 in the selected region, the hand control will display “No object
found in this region.”
• If multiple bright stars appear in the list, users can identify the names of the stars in
the real sky by matching the azimuth, altitude and magnitude provided by the SynScan
hand control.
• Pick one of the star(s) (generally the brightest one) as the 1
st
alignment star and press
the ENTER key to proceed to the next step. Press the ESC key to return to the previous
step (“Select Region”).
