Thanks, Patrick. It should be straightforward to make one, either by laying it out by hand, or printing one using the computer. In either case, one must take care to punch the pinholes at precisely the correct spacing. The more precise the gauge, the more accurately one can judge their pupil diameter. If you find yours at SPOC, perhaps you can scan it? --- Patrick Wiggins <paw@wirelessbeehive.com> wrote:

S&T used to sell a pupil gauge, and I think it was printed in a monthly issue some years ago. I was unable to find it on Sky Publishing's on-line catalog today, however. If someone can search for the issue it was published in and post it, I'd sure appreciate it.
No luck with searching S&T's on line archive either. There were mentions of the gauge but no articles on the gauge itself.
Unless someone has made off with it my S&T pupil gauge is still over at SPOC in the Harmons control room bookshelf. Star party this coming Saturday so maybe we can use it then.
