This Optical Vision filter set comprises 4 high quality glass filters with the following colours: Yellow, Red, Green & Moon/Neutral Density Filters

The Neutral Density - A great filter for the Moon, and for stacking with other planetary filters to increase density without changing the colour. A neutral density filter is also useful when splitting binary star systems (double stars). Use anytime you want to decrease brightness but don't want to affect the colour characteristics of an object.

These filters will fit most internally-threaded eyepiece barrels of 1.25"/31.7mm format. Supplied in attractive foam-lined plastic screw top storage case.
