This is getting toward OT, but my brother had one of those "astronomy" scopes about 4 decades ago, a 3 or 4 inch reflector in a cardboard mailing tube, IIRC. We looked at a solar eclipse by using it to project an image on a piece of white Bristol board. WOrked fine, and no danger to anyone. I wouldn't have known how to hold a sextant at the time, never mind use it.
