[ATM] Swayze's new 10 inch F3

[Daniel Fundo]

Wow....love the woodwork!!

O.K., Mel, we have two successful f/3 designs, your's and Steve's.  

How far can we scale this....16 inch, 20 inch, 24 inch?  Was yours a meniscus like Steve's?  Will this be the way to go?

Will the Parracor (R) work, or is a newer design needed?

In the case of using this low f/ratio for the occasional planetary or other hi-mag application, will the standard Barlows work?

I worked an f/4 12.5 years ago, and it was a bear to get to 1/10 wave!!!  How much harder is the f/3 to work (yeah....I know....inverse ^3 rule <G>)
