Quick Overview

Baader Fringe Killer filter blocks defocused light in the blue spectrum, as well as in the red part of the spectrum (IR) above 700nm, usually seen in small achromat telescopes. The smaller details on craters of the Moon and planetary surfaces are so much more visible! Provides the brightest picture of all industrially manufactured colour error-correction systems. Thus, the Fringe-Killer is a must for small refractors!

Details

Main features:

Provides the brightest image of all industrially produced colour error correction systems. Thus the Fringe Killer is a must for even the smallest telescopes.
Removes blue fringing as well as red fringing above 700nm.
Cancels the devastating intensity of the disturbing purple fringing in a new form, which was never implemented to date in astronomical filters
Even weak nuances remain clearly visible in the planet due to the excellent colour balance.
In conjunction with an RG-610 Red Filter produces a narrowband Ha-pass filter with an only 70 nm wide windows and 95% light transmission - at an incredibly low price!
The combination with the Neodymium Skyglow Filter (with Phantom-Group-Coating) results in a balanced, breathtaking contrast to the observation of fine lunar and planetary details.
Planeoptically polished for perfect sharpness, even when the filter is assembled well before the focal point (or binocular digital camera insert).
No deterioration of resolution with high magnification - as would happen with flame-polished (raw polished) glass, commonly used for all sorts of filters!
Hight Quality Coating: Plasma-enhanced dielectric coatings result in hard, scratch-resistant and waterproof filters. Almost 50 layers on either side, carefully positioned as not to impair the optical quality of the substrate surface
Makes the performance of a simple f/8 economy refractor look like a classic f/15 Fraunhofer achromat. See it to believe it!
