[QUOTE="OPTIC_NUT, post: 3166846, member: 121951"] One of the great things about the old single-layer coatings is they are nowhere near as sensitive to night sky splash. You can tune the coating by thickness, and they chose low green loss and higher violet loss. There is more than just one number to light transmission. I use old 10x50s to resist the Target parking lot splash 1 mile away, or "Haze - 1A" filters tacked onto my modern Nikons. I see many more stars in M42, and more distant detail in the haze on the pond or the beach sanctuary in summer. Better contrast and saturation over 200 yds. [/QUOTE]
