Premium grade H-alpha interline chip CCD-filter for fast optical systems f/10 to f/2.8 and IR-blocked
NO halos, NO reflections, NO ghosting
Baader Planetarium H-Alpha passfilter 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-coloured 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 H-Alpha 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.
Baader's new H-Alpha passfilter enables high-contrast deep sky images of H-II regions (such as the N. American Nebula). Its medium 35nm FWHM bandwidth is ideal for interline CCD cameras ( like SBIG ST-2000/STL11000). The lower sensitivity of interline transfer CCDs benefits from the more efficient 35nm FWHM. The sharp bandpass and > 90% high efficiency coatings make the Baader H-Alpha filter superior to the common coloured-glass based filters, all at a reasonable price.
The Baader H-Alpha filter shares the same outstanding features as all the other Baader imaging filters. Unmatched optical quality, and high efficiency hardened multicoatings result in the sharpest and highest contrast images possible.
