RoboFocus for RCOS Secondary Mirror Focusers...
ROBO-FOCUS is a remote focus driver to be installed on your existing telescope focus mechanism. It provides digital control and input for commands to the stepping motor which is controlled by a microprocessor.
To use the ROBO-FOCUS from a remote location, you send commands from your computer to change the focus position, and receive back digital command information to the stepper motor. You'll check the results by taking a CCD image to judge if the focus is now where you want it. If you are in the observatory, you can also change the focus by using buttons on the ROBO-FOCUS control unit while looking through the eyepiece.
What does this mean for you?
With ROBO-FOCUS, you can make tiny changes to the focus setting so that you can finally take full advantage of the resolution of your optical system for either visual or imaging applications. You can repeat a focus setting at will, and you can always get back to a setting that you found was optimal. And you can make focus changes from your control room or in the observatory.
When you change your optical setup (say, by adding a Barlow), with a simple data point entry you can set the focus to almost exactly the correct position, subject only to the refinement of actual observing. ROBO-FOCUS makes CCD focusing particularly easy. Many users find that they can focus perfectly in only 3-5 minutes after taking only a half dozen fast star images.
RCOS builds and supplies mating components to fit the RoboFocus onto existing RCOS secondary mirror focusers. Installation is simple and fast.
