Now I've just got this hare-brained (hair brained?) idea to enlarge
the hole a bit so that I can insert the 10x lens of my Canon S1-IS,
and make a non-obtrusive spider mount for a small mic capsule
or two at the parabola focus. That way I can photograph what I'm
hearing.
I'll also have to find some sound-deadening goo to put on the dish,
maybe autoparts store rather than plumbing department. Here's
my "nature" recording of the unmodified, unmounted, untreated dish:
