Re: [ATM] Wind resistance & golf cylinders

Wind resistance and golf balls...

Golf balls work because of dimples, and they're going
in a certain direction in relation to their relative
air pressure.  The cylindrical shape of a telescope
may not work like a golf ball if it's dimpled.

Instead, try a wall that reduces your horizon to about
120 degrees.  Anything below that is turbulence,
anyway.

Put up a tent around your scope, and the wind can't
get to it.  The tent serves as a protection for you,
as well, because wind chill can't get to you, either. 
It will also block a good deal of dust from your
telescope if the wind happens to whip it up good.

Tents also offer some privacy...  for those long
exposures.
