Thanks for the information on Bygrave on  ebay, some nice pictures.


"My Mark V seems to have the potential to be more accurate, but I still
need to repaint the bubble lighting system. I have found a workaround
for now. I have a little flashlight that I use to reflect a little light
through the sextant, and that allows me to see the bubble but not wash
out the star. "

I use the same workaround with my A-7.



"Sometimes during a night of good _*sites*,_ I will get some whopping
errors, and I think this is the human factor."
