This variable polarizing filter has a Aluminium material mount, which is sturdy and durable.
It helps you to adjust the brightness effectively. The variable polarizing filter allows for selective adjustment of brightness, which is useful for terrestrial observation.
These filters have a very large range of effectiveness. Light transmission of polarizing filters is between 1% and 40%.
Variable polarizing filters are made up of two individual filters. The variable darkening effect is produced by rotating the lower filter relative to the upper one. And it reduces glare for improved perception of detail and for better viewing comfort.
Fit all 1.25" eyepieces with the standard filter thread.
