1.25" Baader Planetarium Fringe Killer Filter. The REFRACTOR-FILTER for all visual observing and especially for CCD imaging. Dramatically reduces the bluish and reddish "secondary spectrum" of achromatic refractors while minimally altering the color fidelity of the image. Blocks near-infrared wavelengths from 700 to 1150nm for dramatically sharper stellar images in all refractors.

The ultimate contrast filter for all refractive optical systems. Eliminates color error of inexpensive achromatic doublet objectives to provide the highest level of definition while correcting color balance. Surface details on the Moon and planets stand out boldly. You haven't really seen Jupiter's Great Red Spot though your achromatic refractor until you've used this filter.

The Semi-APO filter benefits from all the host of world-class Baader filter attributes. The Semi-APO filter is truly the world's most advanced 'minus-violet' type filter in every regard. It's high efficiency and neutral coloration make it practically disappear in use - while making most of the violet fringe disappear! The effects on sharpness, contrast, and aesthetics are remarkable, even with small refractors.

Baader Planetarium has introduced the world's finest UV/IR cut filter. This filter is a must for all digital imaging with Digital Cameras, CCD Cameras, and modified WebCams. Also useful for protecting valuable H-Alpha filters from heat stress and damaging IR (Daystar, etc).

CCD imagers will find Baader's Premium Narrowband CCD passfilters to deliver 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.
