Description

The filters worked exceptionally well and we got terrific images post-impact. We couldnt have done it without your help, and we are very grateful! Such an exciting and successful mission to be a part of (and lots of observing work).- Magdalena Ridge Observatory (MRO) Director

Key Features

Baader Bessel-UBVRI Bandpass Filter Set, suitable from f/15 to f/1.8
Classic photometric filters with transmission according to Bessel- parfocal with all Baader filters of the same size
Manufactured with most advanced ion beam coating technology / Daylight-Proof
Reflex-BlockerTM hard coated and planeoptically polished- with sealed coating edges (Life-Coat™)
Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
Equally suitable for modern CMOS cameras as well as for older CCD camera technologies

The new generation of Baader CMOS-optimized filters features:

Reflex-BlockerTM coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics
Identical filter thickness to existing standards, with utmost care for parfocality
Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter
Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed read more)
Life-Coat™: evermore hard coatings to enable a non-aging coating for life- even in a most adverse environment

Life-CoatTM

Limited-Lifetime-Warranty for CMOS-optimized Baader filters

A Baader Planetarium exclusive. Filters incorporating Baader Planetariums 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.
