Also I can use the cave at f/16 or as a newt at f/4 What is this 3rd order thing? must of missed the post on that.
Hopefully, John W (or someone else who actually knows about/understands the physics) can weigh in on this
I'm afraid I don't understand the physics well on this- maybe Jerry does, but I have tested the same mask with f4 and f10 and found the pattern to be easy to use with both. I suspect that you will be able to use the same mask even with that wide of a range of f ratios. It's extremely forgiving.
