Lumicon, Thousand Oaks & TeleVue DS filters - spectrum transmission tests

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.

Hi Maurice,

This is excellent information and really shows the differences between
different filters. I'd be interested to see the new Contrast Booster from
Baader and also Astronomik's UHC and OIII filters if you know anyone who has
them?

Keep up the good work.

Very best wishes and clear, dark skies.
