Filter UHC+CLS+Moon+UV/IR Cut Filter Astronomy Telescope Monocular Astronomical Observations Deep Sky Object

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 Anodized 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 of SVBONY 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:

▇SVBONY 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 SVBONY 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 SVBONY 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
