Astrodon 3 nm H-Alpha Narrowband Filter - 49.7 mm Round Unmounted - HA3-50R

Hi Chris. I thought I had one. But it turned out to be an Astronomik 50mm Ha unmounted but 12nm. Never used it. Bought the wrong thing. So there it sits, unloved and unwanted. Sniff!

Thanks Pete. Yeah, 12nm is a little wide. Thanks though.
