New visual filters from Omega Optical.

Sean Walker

Filter manufacturer Omega Optical, a supplier of filters for the Hubble Space Telescope and the Mars Exploration Rovers, has entered the consumer market. They are now offering filters to the amateur astronomy community. The first group for sale includes a UHC-type filter, a UHC/Light Pollution Reduction filter, an OIII filter, and a galaxy-contrast-enhancement filter (GCE). Of note is the GCE filter, which takes a different approach to enhancing galaxy observation by allowing high transmission through nearly the entire visible spectrum while rejecting only the harmful light pollution wavelengths.
