    Is it common for water-filled AH sights to achieve very high accuracies?
    From: Joe Wong

    Took these sun shots several days ago by using my Tamaya and Davis AH,very suprised to find out that these HO229-calculated and plotted LOPs are extremely accurate. Excel spreadsheet results based on actual pos. as AP showed that all the intercepts fall within 0.3 nm with a particular good one fall within 0.1 nm. Although this time I did not stay indoors shooting through the double-glazed window as usual,instead, I took my AH outside and replaced the original AH plexiglass shades with a couple of Schott glass panes, these efforts were intended to eliminate as much uncertainties as possible. but still,I find these results too good to be true.
