This variable polarizing filter made from anodized aluminium and optical glass allows you to progressively reduce the amount of light entering your eyepiece.

Reduces glare whilst increasing contrast so perfect for observing bright objects such as the Moon or certain planets.

Light transmission can be varied from 40% down to as little as 1%.

Will not change the colour of the object being viewed. 

Prevents eye fatigue and loss of night vision.

Each filter set consists of two polarizing filters, one which can be rotated in its cell to adjust the brightness.

The filters, used as single elements, can also be used for daytime terrestrial use for reducing sunlight glare from lakes oceans or window glass.

Available in two sizes, threaded to fit either standard 1.25” or 2” astronomical eyepieces.

Supplied with storage case.
