The GCE takes a different approach to Wideband LPR filters by employing a "Notch" design which excludes all the bad stuff, from 540 - 590 nm, while allowing the rest of the visible spectrum to transmit over 90%. This results in a "wideband filter" that provides a slightly brighter image than traditional single band filters which reject most red light. The GCE excels as a general contrast booster with an absolute minimum of star dimming, and really enhances dark material in the milky way, and even adds some degree of improvement for galaxies. They are also an excellent match for binoculars and the low power-per-inch they offer. And as with all DGM Optics filters features super durable Ion Assisted Plasma Coating Technology.
