CALIBRATION

It is necessary to calibrate the autoguide before the start of the guiding. To do this you

have to complete at least one procedure - determination of the orientation of the celestial

reference frame in the image, taken from the camera. In addition, it is advisable to perform

camera calibration with the dark frame.

Determination of the orientaion of the celestial reference frame

Direct your guide to the star you'd like to use for guiding. Make sure that the star isn't near

the image edge. Focus the image. Make sure that all mountings are tightened and the

wires do not hang freely.

Open 'Processing' -> 'Calibration' from the main menu. The Calibration window is opened

and can be moved if needed for monitoring the guide star.

Use the 'two axes' parameter to choose the two-axes or one-axis calibration. If the polar

axis is aligned, it is recommended to use the automatic mode of calibration - parameter

'auto mode'.
