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
