    I thought the telescope was for stars; isn’t that why it’s called a star telescope.  Don’t high power magnifying glasses burn better holes faster?  I tend to favour my right eye with sextants, because it fits better, but I also know that my right eye is worse than my left, so I try to protect both as much as possible.   Just thinking about it seems to have made this writing go slopey.  I normally just use the sighting tube plus a rubber flange for the Sun (and lots of filter of course).  With a Smiths Mk2, you’re stuck with 2x, but there’s a great big periscopic sextant in front of your face, a really good filter system, and a big floppy eyepiece, so no light gets round the sides.
