FilterThe BAADER Fringe-Killer Filter minimizes unwanted blue fringing, comparable to a MinusViolet-Filter, while retaining a very pleasing color balance. This would be a contradictionin itself – only made possible by applying modern DWDM plasma assisted coating technology,
allowing almost a hundred coating layers to be accumulated onto a planoptically polishedsubstrate – without destroying the optical figure! This fineoptical tool will help a small
refractor to really put the advertized magnification within reach. Performance rivals that of themost expensive color correcting lens systems, costing 20 times as much!
(Note: for solar observation use only in combination with Baader AstroSolar Safety Film!)

Properties:
 Offering the brightest image of all colorcorrecting devices in the industry, makes theFringe-Killer a must for even the smallest ofrefracting (lens type) telescopes.
 Removes blue fringing as well as REDfringing above 656 nm!
 „Breaks“ the intensity of the devastating
false blue color in a completely new way, never
ever before manufactured as astronomicalfilter.
 Forms a „plateau“ of eff. 50 % transmission
in the „blue“ spectral region from 450 nm
to 480 nm – being much more complex toproduce than even the narrowest of all Nebula
Filters.
 Retains the highest light transmission of all
known color correcting devices – be it filters or
lenses – in all important deep sky wavelengths
from 486/501 up to 656 nm. LIGHT is „thehottest commodity“ for high magnificationwork.
 Built-in Infrared Blocker, ranging from 656
to 1150 nm, makes it the perfect tool for CCD
work, as well as afocal projection-photography
with digital cameras for Moon & Planets.
 Subtlest of color variations remain visible inplanetary surface detail, due to the excellent
color balance.
 Fits 11⁄4” or 2“ eyepiece filter threads.
 Combine with our 11⁄4” Red RG-610 color
filter (# 2458307), to receive an ultra narrow(~70nm) wide H-α passband filter of unhearedof 95% peak transmission at world‘s lowestprice!.
 Combine with our 11⁄4” NEODYMIUM Moon- &Skyglow Filter # 2458305 (with Phantom-GroupMulticoatings) for breathtaking contrast on
lunar and planetary surface detail!
 Planoptically polished, means perfect
sharpness, even when mounted way in front ofa binocular viewer, or during afocal projection(digital imaging).
 No deterioration of resolution withmagnification at 300 times or more – as it
would happen with the usual „flame polished“(raw polished) glass, commonly used for all
sorts of filters!
 Coating: Plasma assisted, hardest, scratch
proof and water impermeable dielectric
coatings of almost 50 coating layers on eitherside, most carefully designed to extend equaltension onto either side of the substrate – inorder to retain a highest quality optical figure.
 Will make the performance of a simple
f/8 economy refractor look like a classic f/15
Fraunhofer-Achromate. See it to believe it!
