(4) Choose REC.START in the PEC screen and press SELECT to start recording while you
confirm the guide star is in the center of the cross hairs. Continue tracking the guide star until
the recoding completes. Since your manual operations are recorded exactly, you need to
implement the corrections as precise as possible. It takes 10 minutes in full circle.
On starting the recording the screen is automatically zoomed to the maximum. You can zoom
down for the wide screen with the ZOOM – key, but be sure to set the zoom level at the maximum
when you make the correction. Corrections may be useless in other zoom levels.
During the PEC recording, the guide star may begin slipping out in the direction of the tracking
(in the direction of RA). Use the RA+, RA- keys to keep the guider star at the center of the cross
hairs.
When you start recording, the count starts at 600 (PEC: 600) and will count down. The
STARBOOK-S beeps intermittently for 10 seconds just before the completion of the recoding in
full circle, until the count reaches 0.
*The count may be skipped and the numbers 600 and 0 may not be displayed because of a timing
of the indication.
(5) As soon as the 10 minutes PEC recording has elapsed, PEC Play: xxx (numbers) will come out
on the screen. From this stage the recorded PEC compensation value will be reproduced.
Continuing corrections with the RA+, RA – keys will correct the corrections and will make your
tracking accuracy increase further.
