About the H-Alpha 35nm CCD Filter - 2" Round Mounted...
The Baader H-Alpha CCD Filter allows for high-contrast deep sky images of the H-II regions. Ideal for interline CCD cameras, the 35nm FWHM bandwith of the H-Alpha filter makes this possible. For example CCD cameras such as SBIG ST-2000/STL11000 are great to use with this filter. The lower sensitivity of interline transfer CCDs benefits from the more efficient 35nm FWHM. Compared to common-colored glass base filters, the sharp bandpass and >90% high efficiency coatings make the Baader H-Alpha filter superior amongst comparable filters.
Like all Baader imaging filters, the Baader H-Alpha CCD Filter shares all of the same outstanding features. Because of the high efficiency hardened multicoatings and unmatched optical quality the H-Alpha 35nm CCD filter produces the sharpest and highest contrast images possible.
