I'd intended to get a Moon shot to try out the Air Almanac's "Moon's P. in A." table and finally got the confluence of clear skies, free time, and a moon clear of the trees. I did the reduction using Pub249 tables which seems fitting. I normally struggle to get good LOPs with the Nautical Almanac's methods - the "P. in A." table is considerably simpler and I was not displeased with the resulting LOP.
This was shot with a tripod-supported Kollsman periscopic sextant with electronic averager and used 4 clicks of shade to reduce the glare which is why the Moon appears to be made from Green Cheese.
