    The calibration observation came in at PDT 18:16:26 (IMG 3508) and worked out to 17* 22'. The spread for this Bris seems to be about 7'. Using the limbs as the reference is not as good as splitting the middle of the Sun's image. I made the calibration task harder than it needed to be by using a 200mm telephoto lens to document the moment. The 50mm would have been better.

    The 50 mm DSLR calibration for the Bris Sextant derivative came in at 17* 15.6'. This puts me on the beach at 18:16 today PDT +7. It will be interesting to see how close the camera rough calibration compares to an actual horizon calibration. ( IMG 3462 shows Actual and reflected Sun overexposed)
