A new Yahoo group (Dob-fans) has been formed. Lest we get sucked into the great small refractor vs. Dob black hole , let me hasten to add that we're talking about thermal management/active cooling issues on reflector mirrors.
I've thrown a few posts in to start the ball rolling.
The Group can be found at:
