FocusAide is a complete focusing application for use with JMI, Optec™, RoboFocus™, Van Slyke™, and Meade Microfocuser™ focusers. It comes with software plug-ins for most popular CCD cameras. By integrating your personal computer, focuser, and CCD camera, FocusAide brings you powerful focusing tools to scan or automatically focus your system. Simply take an image, pick a star, and click the Auto Focus button. The rest is automatic and the result is fast and highly precise focus.

Now with:

Temperature Compensation for JMI and Meade Microfocuser Focusers!

The PCFocus control unit now has temperature measurement control for JMI and Meade Microfocuser focusers and the FocusAide software fully supports training and determination of temperature coefficients as well as automatically correcting focus as temperature changes throughout your imaging or observing session. 

Optec and RoboFocus have built in temperature compensation.  With the new PCFocus add-in board and upgraded FocusAide software, other focusers can be driven to adjust the focus at any time including when the temperature changes. With the exception of obtaining temperature from the PCFocus unit, all compensation is done in software running in your computer. This means any focuser that FocusAide can drive can move to a new position that the software has determined is required to keep your system in focus.  Currently, users can auto-focus at any time during a session to "touch up" the focus.  With the new capability previous auto-focus information is stored and used to determine a new focus position if temperature changes.  The result isn't a temperature compensated focuser but, overall, your system will stay in focus through an imaging or visual observing session all controlled in software by FocusAide. 

Current PCFocus users can have their units upgraded to allow the new version of FocusAide to make temperature adjustments.

Here is a screen shot from FocusAide of the temperature compensation control tab:
