Noticed on the DGM site they have now formed a partnership with Omega Astro Filters who make filters and are used by major companies including NASA and have a GCE Filter which is a Galaxy Contrast Filter coming soon.
(Below is a quote from DGM )
The Galaxy Contrast Enhancement filter aids in the visual observation of galaxies and milky way dust clouds and dark lanes. The GCE filter takes a different approach to enhancing galaxy observation by allowing high transmission through nearly the entire visable spectrum while rejecting only the harmful light pollution wavelengths. Because of those attributes it is also a very good general purpose LPR filter, unlike traditional wideband filters exclude most of the red portion of the visable spectrum.
Price 1.25" $80 US 2" $160 US
Mmmmmmmmmmmmmm VERY INTERESTING
