Bruce, Yes please. If you already have them in "soft format" I would appreciate having them. The weekend is coming up so should have a some time to check this out. I used this telescope to take star sights on my Atlantic crossing, but having used the normal scope for sun sights, and being used to a normal scope it was quite difficult to bring star to horizon. I had to consciously countermand what my brain was telling me to do. My Russian sextant is not WW 1 it is a SNO-T Year 1983 serial no 83376.
