    Baader UHC-L / Ultra-L Booster Nebula Filter - 1.25" Mounted

    The Baader UHC-L Ultra High Contrast filter is a dual-bandpass visual and photographic filter. It is meant to block light pollution and increase the contrast of emission nebulae and cometary C2 emission lines. The high transmission gives a much brighter image than other UHC filters. The passbands centre around the OIII & H-alpha lines making this a wide dual-band filter without changing the star colours. The Baader UHC-L filter can be used visually as well as photographically, where it acts as a light pollution-blocking luminance filter, while cutting off the UV and IR ends of the spectrum. Additionally, the UHC-L is suitable for comet observation, as it passes the OIII line at 501nm as well as the two C2 lines at 511nm and 514nm, which are typical for the gas tails of most comets.
