Not much time to blog today but I did want to share something quick from last night. I intended to go out and work on testing some stuff for this IR radiation filter problem, but found I was clouded out.

There is a gigantic Purple Martin roost over at the Umstead Bridge connecting Roanoke Island to Manns Harbor – an estimated 100,000 bird converge at sunrise and sunset.

This is a composite concept I’m working on. Now that I’ve assembled this first version, I do know that I want to go back and capture some more material and try it again.

Speaking of filters – if anyone has any scratched 4×6″ filters they’d like to donate to a good idea – doesn’t matter what they are, I’d be interested. Really just looking for 4×6″ optical resin to test something.
