    Lunar distance sights
    From: Randall Morrow
    Date: 2013 Apr 22, 10:42 -0700

    There have been postings about what level of lunar distance accuraccy can be achieved, but I would like to know what level of accuraccy is usable? Better is "better" of course, but at what point is a sight usable? Of my last 14 lunar sights the average is 0.7' error in lunar distance. The best were 2 sights at 0.1' and the worst 1.3'. The average for 7 moon-planet sight was 0.7' and for 6 moon sun sight it was 0.5. Are these good results? The 30 minutes of longitude error for 1' of lunar distance makes me look disdainfully at my efforts that are not less than a minute. What's the grading standard gentlemen?
