Baader L-RGB-C CCD-Filters

Baader's new L-RGB-C anti-reflection filters deliver improved color separation and image quality without annoying halos. Through an extensive coating stack design and testing program, Baader has partnered with the world's leading thin film coating company to produce transmission curves that border on the ideal. Their ultra steep cutoffs and high transmission (>95%) allowed Baader to do something to a degree no other RGB filter set can manage - they are able to effectively separate the important H-Beta and O-III lines.

Each substrate is fine-optically polished plane parallel to deliver a smooth and accurate 1/4 wavefront over the entire surface. Each filter is blocked and polished individually, not cut out of a larger plate of glass. The special custom polishing operation sets Baader filters apart from the lower optical quality provided by standard commercially precision polished filter substrates used by most other filter manufacturers.

NOTE for Users of the Unmounted Filters: The preferred oriention of the filter is to have the highest reflectivity side facing skyward.

Never use any eyepiece filter for solar observation without objective front filter!
