You could have found something to fill a cloudy week there Frank. Thanks for the link, it looks like it covers most of it.

This is a teriffic resource, Frank. Jeff is the guy I mentioned from Sierra Vista that drove to my house to yell at me for using the wrong filter on my first solar scope! He's a good guy, and one of the smartest guys you'll ever meet. Thanks for posting it.
