[Raytrace] New Here

[Jerald F. Wright]

    Hello to the group.  I'm Jerry Wright.  Just found this group and
looks interesting.
    I've made a 4" f16 doublet using wyld's chapter in ATM3 as a guide.
Used a calculator first but later wrote a program in BASIC for the
raytrace. The lens works good!  Want to make a triplet now and have an
old brass telescope tube with no lens, and think I might be able to fit
a 5" in it.
    I've played with OSLO-LT and gotten lucky with some designs, but
really don't have a clue what I'm doing.  Seems easier with those
glasses that I'd never be able to afford...but maybe I'll eventually
come up with a poor man's triplet.  I'm going to keep it long... f15 or
so... dont want to cut that pretty antique tube.
Jerry
