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.
