Re: [ATM] Luri-Houghton prescriptions.
I've entered all of the designs I got in this thread along with a
few others using one template rather than starting from scratch
so some of the designs probably have the wrong distance from the
lens to the mirror. This is the next thing to investigate. It's
kind of slow work right now because the need isn't there yet for
something to be finished and ready for grinding into real glass.
I also realize that a number of the designs are only
approximations of the exact numbers that OSLO put out and this
does tend to swell the size of the spot diagrams a bit! The
original design produced a typical sized spot diagram compared to
the others but when I got the numbers out to more digits, the
spot diagram shrunk to 10% of what is was.
I've got to soon do a page for this design exercise and then
start For those that want to see where I'm at right now,
http://bobmay.astronomy.net/houghton/ has the files I just
uploaded from my computer. I expect a bit more work to finish
them up but you can see the mess that I've already made of
things.
