Astromania 2" Variable Grey Polarizing Filter

Astromania 2" Variable Polarizing Filter

This variable polarizing filter acts like a dimmer switch for your telescope, toning down the brightness of the Moon or planets to a comfortable level and revealing more surface details.

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.

• 【Easy to Use】Variable polarizing filters are made up of two high-grade glass 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.    
• 【Durable】This variable polarizing filter has a Aluminium material mount, which makes it difficult to be broken.    
• 【Pratical Function】It helps you to adjust the brightness effectively. The variable polarizing filter allows for selective adjustment of brightness, which is useful for terrestrial observation and objects of the Solar System.    
• 【Light Transmission】This filter has a very large range of effectiveness. Light transmission of polarizing filters is between 1% and 40%.    
• 【Fit with 2 Telescope Eyepiece】Fit all 2" eyepieces with the standard filter thread.
