Description
The SVBONY 1.25Inch UHC telescope Filter was designed to improve the image contrast of observed objects. Due to its ability to produce exceptionally sharp and clear images, this filter is considered one of the most popular astronomy accessories. It can be used not only for celestial observations but also for astrophotography. 7D MkII , 7D , 20D , 20Da , 30D , 40D , 50D , 60D + 60Da , 70D , 80D , 300D / Digital Rebel / Kiss Digital , 350D / Digital Rebel XT / Kiss Digital N , 400D / Digital Rebel XTi / Kiss Digital X , / Rebel XSi / Kiss X2 , 500D / Rebel T1i / Kiss X3 , 550D / Rebel T2i / Kiss X4 , 600D / Rebel T3i / Kiss X5 , 650D / Rebel T4i / Kiss X6 , 700D / Rebel T5i / Kiss X7 , 750D / Rebel T6i / Kiss X8 , 760D / Rebel T7i / Kiss X9 , 1000D / Rebel XS / Kiss F , 1100D / Rebel T3 / Kiss X50 , 1200D , 1300D , 100D.

SVBONY UHC EOS-C Clip-on Filter
Sturdy Plastic Case
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.
Notes: The CLS EOS -C is suitable the Camera type:7D Mark II, 80D/800D, 77D/70D/760D/750D/700D 650D/600D, 550D/500D, 400D, 100D/1100D/1200D/1300D. Notes, this Filter is not for EF-S camera Lens.
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.
