Product Description

Optec - #23A Light Red,  50mm diam x 2mm thick

 Blocks blue and green light completely.  Passes light longer than 600nm.  This filter will block the sodium lines from low pressure sodium lights and effectively darkens the night sky from a variety of light sources including the moon.  The H-alpha light from nebulae is passed completely.  A good filter to use when the moon is up.

The Optec IFW Intelligent filter wheel (#17350) is the ideal compliment for holding this filter
