Aubrey- If you are interested, I'll send along instructions from one of the old manuals explaining how to adjust that inverting 'scope. I think it would be interesting make use of it. Just a wild guess, but I have the notion inverting 'scopes went out of fashion around WW I, shortly after lunar distances were dropped from the Almanac. Seems like those full view horizon mirrors didn't appear until the last half of the twentieth century. Does anyone know? Bruce
