Photometric filter set Ø 50,4 mm BESSEL Baader Planetarium

PHOTOMETRIC FILTER SET 50.4 mm DIAMETER BESSEL BAADER PLANETARIUM

• Reflex-Blocker ™ coatings, for the greatest freedom from halos, even in the most adverse conditions related to auxiliary optics
• Filter thickness identical to existing standards, with extreme care for parafocality
• Blackened edges all around, with indicator on the filter cable side in the form of a black outer edge on the telescope side, to additionally eliminate any reflections due to light falling on the edge of a filter
• Each filter individually coated, with sealed coating edge (NOT cut from a larger plate with exposed coatings)
• Life-Coat ™: increasingly hard coatings to allow for a coating that will not age for life, even in the harshest environment

TECHNICAL FEATURES
