Astromania Variable Grey Polarizing Filter Features

• 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.

About Astromania Variable Grey Polarizing Filter

Astromania 1.25" Variable Grey Polarizing Filter Allows for selective adjustment of brightness which is useful for terrestrial observation and objects of the Solar System. You often find considerable differences in detail brightness on objects of the Solar System. This is particularly noticeable when observing: - Moon craters which are close to the lunar terminator - Sun spots and faculae. Caution: only to be used in association with an appropriate solar filter on the front of your telescope! - Details on planets Irradiation from brighter regions prevents you from distinguishing fine details. Variable polarizing filters allow you to selectively adjust the level of darkening. Light transmission: Light transmission of polarizing filters is between 1% and 40%. These filters have a very large range of effectiveness. Handling: 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. Capacity: Connection(to the telescope): 1.25" Type: Polarizing filter Mount material: Aluminium Color: neutral grey Transmission: 1(variable from 1% to 40%)
