More on Curtis' 12" F4 . . .

Out with the old, in with the new. Here's Curtis' 12" F4 OTA
"before and after". It's considerably lighter. Note the two Losmandy
4" dovetails on either side of the OTA. Curtis will be able to
rotate the OTA 180-degrees for imaging, if needed.

The telescope will be mounted on an German equatorial.
