Use the point and shoot camera or equivalent to record CN observations. See the linked images showing the split time of a stopwatch and the corresponding sextant Hs. The stopwatch was started at 18:17:00 6/24/2011 PDT +7. Add the stopwatch's 23 min. 55 sec. to get PDT time of observation of 18:40:55 6/24/2011 or 1:40:55 UT 6/25/2011. Hs of lower limb Sun is 16* 21.2'. A.P. 34* 10.2' N 119* 13.9" W. Height of eye 7 ft.

Getting sharp close-up images may take a few practice snaps to see what settings work best. I used macro ISO 200 priority auto with a 1/3 underexposed meter bias for clear sky conditions.
