    Try different shade combinations to improve lunar consistency. For shading the Moon I like the second lightest shade. For shading bright stars and planets I like the lightest shade. The next thing to try is Frank's pre-lunar calculator. This saves time searching for the bodies and prevents inconsistencies caused by fatigue. I would also avoid taking lunars in windy conditions.


    Personally I'm not happy when lunar errors are over 0.5'.

    Lunar distance sights
    From: Randall Morrow

    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?
