NavList:

I would like to compile a list of instruments that are widely known and referred to as "sextants" but which do not have an angular measuring range corresponding to the traditional definition of that range, which should top out at 120°. For example, many bubble sextants are known as sextants, but are they "technically" sextants? Many measure less than 90°, right? What are some range limits on common bubble sextants? The Apollo spacecraft sextant (last flown fifty years ago, this July) had a smaller range, too. Anyone have that number handy? I've got it in my notes somewhere... somewhere! :)
