Omegon Filters Variable polarizing filter 2" moon observation
2'' variable polarizing filter
Allows selective brightness adjustment, which is useful for observing Earth and Solar System objects.
Considerable differences in brightness details of Solar System objects are often found. This is particularly noticeable when looking at:
- Lunar craters that are close to the lunar terminator.
- Sunspots and faculae. Caution: It should only be used in association with an appropriate solar filter on the front of your telescope!
- Details about the planets
The irradiation of the brightest regions prevents you from seeing fine details. Variable polarizing filters allow you to selectively adjust the level of darkening.
Light transmission:
The light transmission of polarizing filters is between 1% and 40%. These filters have a very wide range of effectiveness.
Driving:
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.
