Neutral density variable polarising filters are the best solution to manually adjust the brightness of bright planetary objects while maintaining the original colour.

Assembly of two separate pieces of glass, this filter is can be rotated to adjust the light transmission between 1% and 40%. This is particularly useful to reduce the glare and the brightness of the Moon, especially at low magnification when the Moon appears extremely bright.

The filters are manufactured from high quality glass and the cell is made of anodised aluminium for high durability.

Available in 1.25″ mounted and 2″mounted cells these filters can be screwed onto most standard eyepieces.
