Jean-Philippe and Alex, Here's the table from the sextant case (translated :o)) Angle � Correction '' 0 0 10 +3 20 +13 30 +18 40 +25 50 +28 60 +36 70 +38 80 +46 90 +52 100 +50 110 +51 120 +48 It belongs to Freiberger Trommelsextant No. 080103 (w. full sight mirror), bought early 2009, so likely manufactured 2008. plotted corrections are fairly well resembling a sine curve, which is why I assume eccentricity as the main source of error. Any other ideas? Wolfgang
