SKG is implemented as a multi-threaded software. Each loop runs concurrently. The role of the focusing loop is to calculate the focus error, and the correction values.


The focusing loop is controlled by the following toolbar:  

Except the connect/disconnect focuser buttons all other toolbar buttons are grayed out when the acquisition loop is not running.

Connect focuser

This button is grayed out when the focuser is connected.

Disconnect focuser

This button is grayed out when the focuser is not connected.


Once the acquisition loop has been started, the following buttons are enabled:

Focuser calibration

Start focusing loop

This button is grayed out if the focuser has never been calibrated.


Once focuser calibration or focusing loop has been started, the following buttons are enabled:

Pause focusing

Stop focusing

Resume move focuser

This button is grayed out when the focuser move is enabled.

Suspend move focuser

This button is grayed out when the focuser move is suspended.


The focuser relay is controlled by the following toolbars:

All buttons are grayed out when the acquisition loop is not running.


The first toolbar allows to move the focuser to the given absolute position.

The move focuser to absolute position button is grayed out if the focuser is not absolute.


The second toolbar allows to move the focuser inward or outward by the given number of steps.

The  button is grayed out if the focuser is not relative.


To move the focuser through the focuser relay, enter the position or the increment in steps and press the move focuser to absolute position or at least one directional arrow button.
