First use: mount alignment
!
All computerized equatorial mounts, in order to allow the automatic pointing of antenna, will need to be aligned to
the stars in the sky. The alignment procedure must therefore be carried out at night and in good weather condi-
tions without clouds. It also depends on which mount is used (so you can refer to the manual of your mount), but in
general, the mount asks you to confirm the date, time, location (latitude and longitude of the place of observation).
Then it ask to point 1, 2 or 3 star alignment of your choice. You can follow these steps pointing at the stars in ali-
gnment with the finder as it was previously aligned with the radio telescope antenna.
!
We continue the alignment procedure recovering from the previous paragraph:
A) with the mount turned off, loosen the clutch of the Right Ascension and Declination motions and point the an-
tenna towards the North Star

B) Turn on the mount and set-up all initial data as described in previous paragraph. The display will show "Begin
Alignment? 1) YES 2) NO": press the 1 button to start the alignment procedure. You can then choose between
alignment with 1 star (1-Star Align.) 2 Stars (2-Star Align.) or 3 star (3-star align.).
!
C) The LCD display shows the message "Alignment" (Alignment) in the first line. Using the scroll arrows, select an
alignment method in the second line of the display, press ENTER to go to the next step or ESC not to do the
alignment.
