OIII spectrum test of Lumicon, Thousand Oaks & TeleVue filters etc

I've added to my webpage

http://home.freeuk.com/m.gavin/grism2.htm

perhaps the first independent tests of the spectral transmission of
eight deepsky filters that include OIII planetary neb filters by
Lumicon, Thousand Oaks and TeleVue and Lumicon UHC, Swan [comet] and
DS filters.

The H-beta [emission neb] and twin OIII lines referenced and HPS, LPS,
mercury lamps.

I'd be interested in feedback.
