Temperature compensation

Temperature compensation in AstroLink 4 Pi is implemented linearly. So there is only one parameter
that describes how temperature affects the focus point. It is not a perfect approach, however, its
accuracy is good enough for most amateur setups.

How to determine the temperature compensation coefficient?

The best way is to note the focuser position at different temperatures. When during session
temperature changes, the focuser position needs to be adjusted to maintain a sharp focus. When you
note these points of temperature and corresponding focuser position, then it is pretty
straightforward to calculate the compensation coefficient, i.e. the number of focuser steps required
to compensate for one-degree temperature change. And this value needs to be entered into the
Temperature coefficient field in the Options tab. When decreasing temperature requires the focuser
position to decrease, then the value will be positive.

How to use compensation?

Once you enter the compensation value into the Temperature coefficient field, you need also to
enable the compensation. Actual compensation is performed once the calculated focuser position
correction is larger than half of the critical focus zone. CFZ value is calculated and presented at the
Main control tab.
