Reduces glare, increases contrast and maintains night vision.

A Variable Polarising Filter is essentially two polarising filters, one screwed into the other. Simply rotate one in its cell to reduce brightness from 40% down to as little as 1%.
Manufactured from optical glass with a neutral density (so no false colour) mounted in a machined black-anodised aluminium cell.
The filters can also be used individually for terrestrial daytime observing to reduce sunlight glare from lakes, oceans or window glass.
Available in 1.25” or 2” sizes to fit most astronomy eyepieces and accessories.
