- Reduces brightness and improves contrast and fine detail in terrestrial and bright astronomical images
- Maintains true color balance
- Stackable with other 1.25" filters or with a second polarizer to create a variable polarizing filter
Like a pair of sunglasses, a polarizing filter reduces by a factor of two the amount of light passing through an eyepiece and into your eye. Reducing image brightness can help improve contrast in terrestrial viewing and imaging, especially in daytime photography. A polarizer also helps when viewing the Moon and planets by reducing brightness and glare to make it easier to see fine detail. It can also make it easier to split bright binary stars in dark sky by reducing glare and diffraction rings around the brighter star of the binary pair.
This GSO polarizer maintains true color balance by reducing the brightness of all colors of the optical spectrum. While the amount of light blocked by a single polarizer is fixed, this polarizer can be stacked with a second polarizer to create a rotatable variable polarizer for less money than a dedicated variable polarizer. Has a standard 1.25" male filter thread (M28.5x0.6) on one side and a female thread on the other side, so you can stack this filter with other 1.25" filters.
The filter comes in a protective plastic storage box. Metal filter cell with high quality optical glass substrate. Made by GSO in Taiwan.
