SVBONY Telescope Filter 2" MOON / UV-IR/CLS Cut Filters Set For Deep Sky Visual

Description: Product Description The SVBONY City Light Suppression broadband filter is designed to improve the visibility of various Deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow). Together with the highly transparent in main nebula emission lines at OIII(496nm and 500nm), H-beta (486nm), NII(654nm and 658nm), H-alpha(656nm) as well as SII(672nm), the filter is suitable for enhancing the contrast and details for both visual and photographic purpose at sub-rural area. 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. Package Includes SVBONY 2"CLS Filter Sturdy Plastic Case The SVBONY 2" filter is a must for all digital imaging with Digital Cameras, CCD Cameras, and modified Webcams. The UV-IR-Cut filter uses the very latest coating technology, to deliver the finest filtration quality - and lifetime durability. If you use DSLR camera, CCD camera, or telescope, it absolutely will be one of your the best choices. Main Features: The SVBONY 2" UV/IR CUT Filter Infra-Red Filter CCD Camera Interference UV Filter True optical quality glass substrate and coatings, to deliver the sharpest images possible Very low reflection multi-coating, Striate-free, and plane-parallel substrate Standard 2inch Filter threads for 2" eyepieces and other accessories Comes with a plastic box to keep it safe and clean when not in use Package Includes SVBONY 2" UV/IR Cut Filter Sturdy Plastic Case This SVBONY Filter is a good moon viewing accessory. A broad spectrum of light transmission means it does not block as much as a DeepSky filter such as UHC, OIII or CLS. But is a good all-rounder filter suited to many applications, including the observation of the moon and planets (DeepSky filters are not designed for this). Features: Metal construction, comes in a clear hard case with foam lining Mild darkening of the sky background for enhanced contrast Reduces glare for the observation of the moon for a more comfortable viewing and to increase the ability to catch faint details The filter will fit all standard sized 2" eyepieces and accessories. It is mounted in a nicely anodized housing. Usage: The filter thread after thread eyepieces, rotate the filter into the eyepiece can be used Package: SVBONY 2" Moon Filter Sturdy Plastic Case about svbony
