Product Details

  • These Baader CCD Narrowband 1-1/4" Filters are the perfect addition for your SBIG STL (or similar) camera to deliver extremely high contrast, short exposure deep sky images in H-Alpha, H-Beta, Oxygen-III, and Sulfur-2.

    The narrow bandwidths for this set of filters have exceptionally high transmissions while simultaneously rejecting light pollution and blocking longer wavelengths.

    Baader employs a high quality polishing system that delivers a smooth, precise 1/4 wavefront over the entire filter. This ensures that you will not lose any sharpness or contrast in your images!

    You will no longer suffer from dealing the reflections that are standard in other narrowband astro-filters due to Baader's careful design and testing of the filter coating stacks. The coatings are masterfully applied by equipment that ensures high consistency for bandpass centering, transmission, and out of band blocking. The coatings won't have any degradation due to use or normal cleaning due to the ultra-hard ionbeam deposition in the coating process.
