Hollywood knows NOTHING about telescopes

I was suffering thru this pot-boiler, and hanging in there pretty well until they got to the part about attaching the "farm implement" to the telescope, the owner of which described it as being a "Cassegranian" scope. Well, a Cass is short and sort of squat, and usually of a significant diameter, while the scope in the movie was long, slender, and most obviously a refractor. Secondly, it was installed in what appears to be the hayloft of a barnlike building, which guarantees that there would be so much vibration as to render the scope essentially useless. Then, thirdly, the capabilities of this scope, a pretty decent sized one, was described by the owner as "And, you can see the craters on the moon with it!!". Well, duh - you can see the lunar craters with a decent pair of binoculars.

Anyway, when I run into absolutely stupid writing like that it takes me completely out of the movie. I gently retrieved the disc from the player, and carefully relegated it to the nearest wastebasket.
