    Re: Sextant camera: TV viewing

    Jim,

    Attached is a LAN capture taken from Channel Islands Harbor north jetty using a DSLR with a 135 mm lens through a Cassens & Plath whole horizon sextant (scope removed). Camera clock records PDT to the second.

    Details:

    a.p. Lat. 34° 9.5' N Lon. 119° 13.5' W
    H.E. 16 ft.
    I.E. 0.0'
    Temp 78° F
    Press. 29.91 in

    Hs 77° 3.5'
    UT 20:02:56 7/15/2013


    Each pixel is 0.145 minutes of arc using the 135mm lens. The image looks to be right on so no adjustment to Hs is needed.

    Greg Rudzinski
