I tried some very long Lunars (up to 137d) with my SNO-T and backsights with a pocket sextant (up to 140d). This is very tricky. I suppose the example in Bowditch is given for illustration only.

No need to remove the stop screw - I was just trying to figure out whether a problem in the 1977 Bowditch of a back sight with a sextant altitude of 141d 04.9' was realistic or just some arbitrary example.
