Fringe-Killer Filter - 2" Round Mounted

The Baader Fringe-Killer Filter minimizes unwanted blue fringing, comparable to a Minus-Violet-Filter, while retaining a very pleasing color balance. This is made possible by applying modern DWDM plasma-assisted coating technology, allowing almost a hundred coating layers to be accumulated onto a planoptically polished substrate. The high transmission and fringe reduction work great for both planetary and deep sky imaging. Baader has included their renowned UV/IR Cut coatings as part of the Fringe Killer formula, with these coatings maintaining very high transmission and well placed sharp cutoffs in the IR and UV.
