When the workload around here gets reasonable and I can devote an evening to it, I'll make some annotated screenies from my bino planning software (REALLY crude, in QBASIC). Perhaps I'll show setups with a particular objective f.l. and f/ratio coupled with a fixed field stop diameter, changing only the prism parameters.
If you wish to, you can still download from S&T this software to play with yourself. It was submitted along with the article I wrote about my home-made right angle binos for the July 2002 issue.
Get it here:

Home-made 11X50 right angle bino, 8.1 deg. FOV
Modified 26X100 bino, 3.5 deg. FOV
