SVBONY 1.25'' Telescope Filter UHC+CLS+Moon+UV/IR Cut Astronomy observation

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.
Features of the UHC Filter :
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
Pls note:
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.

SVBONY 1.25 inch UHC 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.
Features of the CLS Filter
:
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.
