Guiding - ZWO ASIAIR PRO User Manual

Guiding

On Preview , Autorun and Live mode screens you can simply touch the guiding graph
pane to enter the auto guiding setup controls.
On the guiding page: On the left side is the you can turn the guiding graph on and off,
and on the right is the guide cameras settings.
Tap this button for the guider calibration data. The graph shows the movement of
the star formed by the guide pulse sent by ASIAIR during calibration. The line
represents the RA and Dec guide star rates calculated as a result of the calibration. They
should generally be approximately vertical.
After setting the EXP exposure time, touch this button to start refreshing the image
captured by the guide camera in real time. It is generally recommended to set the
exposure time to 1-4s.
Start calibration. Before tapping calibration, you can also manually select a star.
Note, do not select the brightest star, generally choose the medium brightness on the
image with a HFD of 3-6. You can also tap the button directly, and ASIAIR will automati-
cally select a suitable star for you to start the calibration process. After the calibration is
completed, guiding will be turned enabled.
Touch this button if you want to stop guiding.
Normally you just need to keep the default setting of these options. However, some-
times the guiding graph can be very volatile. In this case you can tap the "show/hide"
button on the far right, see the corrections signs and slightly adjust the value of "DEC
Aggr" and "RA Aggr" to help flatten the guiding graph.
When you complete the calibration work and get the ready for guiding, please
first wait for 10-20 frames and then tap the clear button on the left side of the
guiding graph for the previous guiding graph and the value of total error might
not be that correct.
