Refractor Telescopes Presentation

[bill-pellerin]

Hi everyone;

Here's my novice presentation (9/5/2014) on refractor telescopes (in PDF format -- because it's smaller than a ppt). I added a slide to mention -V filters for refractors that are not fully color corrected.

Clear skies!

Thanks, Bill

I want to build myself a little spread sheet that combines all your math slides so this will be a handy reference.
