Kearn, there is one scene you might cringe at. I did!
Two astronomers are at the South Pole

with a 12" - 14" SCT pointing straight up (coz they are at the South Pole

) and coz it's pointing straight up, the corrector plate keeps filling with snow. Well, this 'Astronomer' uses a plastic (or wood or metal

) scraper to scrape the snow of the corrector!!!!! Roughly!!!!!!!
Be nice to have a budget where you just don't care if you wreck it. Just pull another one out of the storeroom! The ESA is paying for all the research.
