Baader Planetarium delivers the latest tool in the planetary imager’s bag of tricks. The Baader IR-Pass filter blocks wavelengths below 670 nm. At these longer wavelengths planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). By combining a luminance image taken with the IR-Pass filter along with RGB frames overall image sharpness … Continue reading

CCD imagers will find Baader’s new Narrowband 7nm H-Alpha passfilter to deliver the absolute highest contrast deep sky images of H-II regions with the shortest exposures possible. Its narrow 7nm FWHM bandwidth has a transmission at H-Alpha of over 90% while completely rejecting light pollution.The high optical quality of the Baader 7nm H-Alpha filter guarantees … Continue reading

Delivers the absolute highest contrast views of many diffuse and planetary nebula. For many objects the Baader O-III reveals a level of intricate detail that rivals the best deep sky photographs. Our favorite filter for the majority of nebula especially The Veil Lagoon (M8) Swan (M17) Ring (M57) and Dumbell (M29). With a large scope … Continue reading

The Baader Planetarium Moon & Skyglow (Neodymium) filter brings an entirely unique approach to contrast enhancement and light pollution reduction. Based on earlier research at Carl Zeiss Baader has developed a new filter that uses Neodymium glass which filters out a few specific wavelengths from streetlights as well as skyglow from the Moon. The unique … Continue reading

Much more than a simple minus-violet filter. Based on the popular Baader Moon&Skyglow filter the Baader Contrast-Booster takes contrast enhancement and skyglow reduction to the maximum level possible from a filter. Not only does this filter deliver a significant enhancement of planetary and lunar contrasts but it is designed to also totally eliminate the damaging … Continue reading

Achromat owners rejoice! Baader Planetarium has taken minus violet filtration to a new level. The Fringe Killer brings a type of filtration never before seen to the amateur. Rather than simply trimming the shorter wavelengths at a chosen wavelength and slope like all other minus violet filters the Fringe Killer carefully attenuates a specific region … Continue reading
