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.
Use of special photography filters, especially narrowband filters, often results in dim images which can be difficult to focus. Baader Planetarium Clear Filters can be used first to clearly focus the image. Since they are parfocal with other Baader filters, they can then be removed and replaced by other imaging filters, without affecting focus.
