Baader Planetarium 8nm SII CCD Filter, 2" Mounted
- Baader Narrowband S-II (8nm) CCD-Filter - 2" # FSIIN-2 2458431
The Baader Planetarium 8 nm SII CCD Filter delivers the absolute highest contrast deep sky images in H-Alpha, H-Beta, Oxygen III and Sulfur-II, with the shortest exposures possible. Their ultra-narrow bandwidths have extremely high transmissions, while completely rejecting light pollution as well as the important blocking of longer wavelengths.The high optical quality of the Baader Oxygen III filters guarantees no loss in sharpness or contrast. Each substrate is fine-optically polished plane parallel to deliver a smooth and accurate 1/4 wavefront over the entire surface. This special custom polishing operation sets Baader filters apart from the standard commercially precision-polished filter substrates used by most other filter manufacturers.Coatings are professionally applied by the most sophisticated equipment available, ensuring high consistency for bandpass centering and transmission. The ultra-hard ionbeam deposition ensures the coatings will never degrade from use or normal cleaning. In addition to their transmission properties, the Baader coatings were developed with another key goal in mind - eliminate the annoying reflections present in other narrowband astro-filters. To achieve this freedom from reflections, along with excellent out of band blocking, required careful design and testing of the coating stacks.Coatings are professionally applied in Germany by the most sophisticated equipment available today, ensuring high consistency for bandpas
