I have been collecting lunar distance data over the past several months to try developing some stats. I have begun to notice an issue when taking lunar distances between the sun and moon when the moon is very faint i.e. in the order of 10% illuminated. In a series of 5 sights, the average error as per the on line lunar distance I am seeing a systematic error in the order of 1.5 minutes. For some reason I am not measuring a large enough angle. As soon as the moon gets to 25% illuminated or better or the sighting is done with a star or planet, I obtain results that are typically within 0.3 minutes. Again this would be the average of 5 sights. Has anyone else experienced this? --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
