Designed to have lower blue spectral shift with faster optics and 3 nm filters can be used on systems to f/3.

Produces a >97% transmission throughout spectral region

Generation II 50mm Square LRGB Filter Set is designed to fit directly into the FLI CFW-4-5 Precision color filter wheel, as well as other wheels that use the 50mm square format.

Photometrics UVBRcIc Filters achieve the highest transmission possible for fainter objects.

Designed by Fukugita et al. to include five mostly non-overlapping filters covering 300 nm to the sensitivity limit of silicon CCD cameras near 1100 nm.

UVenus Filter will allow you to image the cloud structure of Venus and Jupiter with CCD cameras on a telescope.

With the Hydrogen-Beta line of the spectrum isolated, the Astronomik 12nm H-Beta filter can detect faint nebulae like the Horsehead, the Cocoon, or the California.
