Colour filters damp light and glare, enhance contrast and resolution by selective filtering and reduce exhaustion of the observer´s eyes.
The more experienced observer will find these filters an essential addition to their astronomical equipment set. Their effectiveness is dependant on factors like aperture and focal length of the telescope, the actual magnification and the viewing conditions.
Baader eyepiece filters can be screwed into nearly every eyepiece. Their quality is superior to standard flame-treated colour glass filters and have an effective anti-reflective coating.
The 7-layer anti-reflective coating on both sides with only 0.25% reflectivity per surface is the most complex coating group ever applied to colour filters. The filter substrate (2 mm thick) is screwed in blackened aluminium mounts and comes with a robust filter box. Every filter is suitable for multiple applications.
