Thanks, Don. I like my old Lumicon filters best, too. Some modern filter purveyors don't include graphed bandpass data for the individual filter. Lumicon always did. On Mon, Apr 13, 2009 at 8:57 AM, Don J. Colton <djcolton@piol.com> wrote:
Chuck,
I have both a 2" Astronomik UHC filter and a 1.25" Lumicon UHC filter. I bought the Astronomik several years ago so things may have changed, but the Lumicon filter is clearly superior.
