Does anybody know a supplier of a 37mm 23A filter? We have Apple's
Quicktake150 digital camera with an adaptor (to 37mm) and close-up
lenses, now all we need is the 23A filter and we can start taking
pictures of our EtBR-stained gels. Any help would be much appreciated.
(I've sent inquiries to rec.photo.misc and .marketplace, as well as
rec.video, with no luck.)
