[Raytrace] where to start?

[Joe Mayenschein]

I like this idea.

And if we actually work out a step by step an actually constructable scope. all
the better.  Like One i have been thinking of,,(he he he)  but yet have been
able to figure out how to get it into the $#%&!#* programs. he he he.

It starts out as a simple 10" f- 6  Newtonian.
