John
thanks
for the reply. I have been toying with the idea of building a 22" f 6. That
would make the focal length 11 feet long. I wonder if it's worth it
having to climb a 10' latter.
I made
a 12.5" f 7. It should be about a foot shorter than yours. I am kind of
wishing that I had made my f 8 now. Oh well.
Jim
