With your guide star on the screen, place the cursor using the UP button on the page numbers
on the bottom right. By pressing SET you can toggle between the pages, and for calibration
select page 2/5. On that page, move the cursor up to "calibration" and press SET.
On the Calibration screen mark "Delete cal." if a previous calibration has been saved, or if
not, just press "Calibrate" . Watch the calibration routine run, first moving DEC, then moving
RA, and finally finishing and outputting some values. Orthogonality is good over 90%.
The mount is then driven back to the pre-calibration starting position, and when finished,
("Press any key to continue") press ESC twice to return to the guiding window.
Start Auto guiding
Now comes the fun part...
Place the cursor on the page switch at the bottom right, and by pressing SET or LEFT, toggle
to page 1, mark "AG start" and press SET. That's it. You're off and running. You have started
auto guiding!
A few additional remarks to help get acquainted with your MGEN:
- On page 1 we see the same values that we saw on the earlier live view screen: gain, exp and
threshold. Threshold is set to 10% by default, to reduce noise. If you have a weak guide star,
you can lower this value a bit, or increase gain or exposure, but not so much that noise starts
appearing. Do not select a guide star that is too small (1 pixel) as it prevents the sub pixel
calculation of the star center.
- on pages 3 and 4 you can adjust the values that influence and fine tune your guiding.
Place the cursor on the page number and toggle using LEFT or RIGHT or SET.
