Description

After two hard years of development and significant investment in R&D, the new Baader CMOS optimized (ultra-) narrowband and highspeed filters are imminent. The new range of Baader CMOS Optimized filters, consisting of 84 filters, finally and cost-effectively tackle the problem of filters being accused of creating unbearable halos when put into close vicinity of correcting lenses – in conjunction with latest generation CMOS-chips.

This new generation of Baader CMOS-filters features:

Increased contrast
Ever more narrow passbands
Reflex-Blocker™ coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics
FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio
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

Baader H-alpha / O-III / S-II f / 2 Highspeed Filter Set - Precision Grade
6.5 nm FWHM, recommended for extremely fast optical systems from f / 3.4 to f / 1.8
Specially designed for the special filter requirements when used with fast optics like the Celestron RASA astrographs
Reflex-Blocker ™ hard coated and planoptically polished - with sealed coating edges ( Life-Coat ™ )
Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim
Optimized for modern CMOS cameras, but excellent for CCD camera technologies
