    Description

    CLS Features:
    Multi-layers anti-reflection coating
    Non-cementing optical substrate coating
    Electron-beam gun evaporation with Ion-assisted deposition coating technology for durability and resistance to scratching, as well as stability on CWL (central wavelength) no deviation affected by temperature change.
    Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and Optical density of off-band.
    Ultra-thin filter cell minimize vignetting by maximize possible
    Aerometal Material Precise CNC Machining Sand Blasting
    Process Black Anod
    ized Finish Extinction Treatment to Prevent
    Reflection Laser Engraving No Fading 90% transmission of main nebula emission lines (i.e. Ha 656nm, OIII 496nm&500nm, SII672nm and H-beta 486nm).
    0.1% transmission of off-band, specifically the major emission lines of artificial light pollution (i.e. Na 589nm, Hg 435nmand 578nm).
    Suitable for color CCD cameras and unmodified DSLRs
    CLS with wider pass-band than UHC and hence is more favored when observing under mild to moderate light pollution.
    Light pollution filter do not eliminate the effects of light pollution or increase the object ' s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.
    WARNING:
    The filters  are not designed for sun observation. DO NOT LOOK AT THE SUN WITH SVBONY FILTER. You would be BLIND if you fail to observe the warning.
    MOON  Features:
    1.25" Moon filter for telescope eyepiece
    Premium Quality Metal Rim and Glass Lens
    Fit standard sized 1.25" eyepieces and accessories
    Mounted in a nicely anodized housing
    The filter has a mild effect of darkening the background of the night sky so that the fainter objects are more clearly seen contrasted against the blackness of space
    UHC Features:
    Brand New 1.25" UHC filter
    Sky background is darker for observations of deep-sky objects
    This filter is perfect for observation of faint and low-contrast deep-sky objects. These features make it perfect for observing nebulae and other deep-sky objects
    Barrel diameter: 1.25'' simply attach to eyepiece-cased in a sturdy transparent case
    Significantly reduces light pollution, great for city and suburban observation
    UV/IR CUT Features:
    The 1.25" UV/IR CUT Filter Infra-Red Filter CCD Camera Interference UV Filter
    True optical quality glass substrate and coatings
    Very low reflection multi-coating, Striate-free, and plane-parallel substrate
    Combine with any of the other Baader filters, to deliver the sharpest images possible
    Standard 1.25 inch Filter threads for 1.25" eyepieces and other accessories
    Comes with a plastic box to keep it safe and clean when not in use
    Interface Threads: M28.5*0.6
