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.

Life-Coat™: Limited-Lifetime-Warranty for CMOS-optimized Baader filters
A Baader Planetarium exclusive. Filters incorporating Baader Planetarium’s Life-Coat™ technology are so durable that Baader Planetarium warrants the coatings for the life of the filter. Baader Planetarium has developed Life-Coat™ using materials and processes that result in coatings which will not degrade or fail for a lifetime. Life-Coat™ coatings resist moisture, temperature extremes, and are hardened to withstand normal cleanings.
Baader Planetarium guarantees their Life-Coat™ coatings will not peel, flake or physically degrade and will withstand repeated cleaning with fine optical cleaning equipment. The Limited Lifetime Warranty applies to the original purchaser and does not cover failure from mis-use, physical damage through improper handling, or improper cleaning.

- Country of Manufacture: Germany
- Baader Planetarium Warranty: Baader products are warranted for two years for flawless optical function (not necessarily cosmetic optical appearance).
