Dear James,
SNO-T sextant is basically a Russian copy of a Freiberger sextant. It
usually came with two telescopes, a low-power Galilean telescope giving a
direct image of the horizon and the stars, and a higher power astronomical
telescope giving reversed images and equipped with a crosshair reticle.
I prefer to use the galilean telescope because it's more comfortable and its
power is in my opinion more than enough.
I don't know if your sextant came along with an english instruction booklet,
anyway i've got one and I've recently scanned it and put it in .pdf format
for other members of this list.
it's quite a big file (approx. 6.5 Mb), if you want I can mail you a copy.
Bests,
Federico
