Important Note About Torn Baader Filter Seals:
Recently, Baader started applying a new filter label on many filters that goes over the edge of the case and also acts as a seal. Unfortunately, these labels rip far too easily during transport, giving the false appearance that the filter case has been previously opened. Many filters we now get from Baader arrive like the ones shown in the photos below, and many others will rip en route from us to you. Rest assured that ALL filters we ship to you are brand new and unopened as received from Baader, whether the seal is intact or partially/completely ripped.

Baader has agreed to revert to their old design of 2-piece labels, but until they use up their current labels, we will continue to have this problem for a while and you might also get a mix of different filter label types. Thank you for your understanding.
The Baader Double Polarizing Filter reduces extraneous light and enhances contrast when observing the moon and planets. This planoptically polished filter has a rotatable element to let you precisely adjust the transmitted light from 30% to 85% to match your telescope's aperture and your observing target. It threads onto just about any 1.25” eyepiece. The filter can also be used for solar observation, but it MUST be used in conjunction with a primary white light solar filter to avoid permanent eye damage.
Manufacturer part number: 2408340 or FPOL-1D.
