TS-Optics Variable Polarizing Filter for telescopes - 2" - variable brightness - for reduction of glare during lunar and planetary observing
The TS-Optics variable polarizing filter can be used on all 2" eyepieces. Its job is to reduce the relative brightness of the object to make viewing more comfortable. This also often means that you will be able to see more detail. Main use of the filter is for observing the moon and the bright planets. The filter offers a neutral grey image throughout most of its filter range. Brightness can be adjusted approximately from 1% through 40%.
