    Camera FAR 2nd Ed.
    From: Greg Rudzinski
    Date: 2012 May 29, 18:12 -0700

    The second edition of the camera FAR has a 1 in. x 1 in. cut microscope slide glass attached and angled between a pair of 52 mm linear polarizers. This can be called a camera FAR system which is then stepped down to 49 mm so that it fits a Pentax 50 mm prime lens. There are two reflections at 14* 23' and 28* 46' for a theoretical maximum observable altitude of 52*. An initial trial at the beach was performed with intercepts in the 2' range. Sea trials will naturally have a larger intercept range. The attached image is for an altitude of about 39* with the camera pixel angle measuring about 10* between the horizon and the second reflection of the Sun.
