Newbie questions... with a twist

Hi Gillaume, At CARA at Antartica, there was one Telescope called
SPIREX which was made by a Scientist/Astronomer/Engineer I know, which
did use 2 Celestron 11" SCT Telescopes as Guide Scopes for the Main
Scope, which I believe was doing reseach in the Infrared Wavelengths.

That being said, it is then possible, probably with the correct
modifications, to use a commercially available scope at the S-Pole.

Sorry for my earlier post in somewhat disbelieving you staying a winter
in Antartica.
I cannot even fathom/comprehend what it must be like at the bottom of
the world during this time of year! Temperatures at which Steel can turn
into Peanut Brittle.

I wish you the best of luck, a safe trip, and hope you figure something
out for a usable scope to enjoy. Mark
