"I'm wondering if the laser measuring devices that you can get at home improvement stores would also work for this..." Speaking of off-the-shelf devices, one can buy a digital level for about a hundred bucks that will read out angular tilt relative to true level accurate to +/-0.1 degrees or so. Stick a sight tube on top of one, and you can measure altitudes simply by aiming --point and shoot. Unfortunately, this throws away one big advantage of the sextant which is that it is not particularly sensitive to motions of the observer's hands. -FER 42.0N 87.7W, or 41.4N 72.1W. www.HistoricalAtlas.com/lunars --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
