THIS IS A BRAND NEW ORION 2" SKYGLOW FILTER. MY WIFE GOT ME A SECOND ONE WITHOUT KNOWING I ALREADY HAD ONE. IT WAS RECEIVED TOO LATE TO RETURN IT AS A BIRTHDAY GIFT. I HAVE USED THE ONETHAT IS IDENTICAL TO THIS EXTENSIVELY IN AN URBAN SETTING WHERE LIGHT POLLUTION IS SOMEWHAT SIGNIFICANT. THIS ALLOWS MUCH OF THE LIGHT FROM NEBULAE AND STARS TO BE SEEN BUT EFFECTIVELY BLOCKS STREETLIGHTS AND THE LIGHTS FROMNEIGHBORING
HOUSES. I HAVE TRIED ORION'S ULTRABLOCK YET IT REDUCES LIGHT TO UNACCEPTABLE LEVELS REDUCING THE SURFACE BRIGHTNESS OF NEBULAS AS WELL AS STARLIGHT, BY AS MUCH AS .5 MAGNITUDE.
THIS IS A VERY HIGH QUALITY FILTER AND I CONSIDER IT THE BEST FOR URBAN SKYGLOW WHERE I CAN BARELY DETECT 4.5 MAGNITUDE STARS. THE ENHANCED CONTRAST IS REAL. THUS, THIS GETS A GREAT WORKOUT ATTACHING IT TO MY 2" DIAGONALS IN A C9.25" AS WELL AS A GSO CLASSICAL CASSEGRAIN. I'M SELLING THIS AT A GREAT PRICE. ORION IS ASKING 0 FOR THE 2" DIAMETER SKYGLOW SO MINE IS A BARGAIN. PAYPAL ONLY AND WILL SHIP FREE TO THE LOWER 48 ONLY. GOOD LUCK AND THANKS FOR LOOKING!
