The IFocus Ocular is Software Bisque's specially designed eyepiece to help you focus your CCD camera quickly and consistently. Here's how it works. You insert the IFocus Ocular into your telescope in place of your CCD camera. You then focus with your eye, just like you do when observing. (To aid you in focusing and centering, the IFocus Ocular provides a circular field of view that is similar in size to the CCD camera's field of view.) Once you are focused, you simply replace the IFocus Ocular with your CCD camera. Because the human eye does such a magnificent job of averaging optical and atmospheric effects, you achieve the best focus very quickly, drastically increasing your image acquisition productivity!
