- Process black anodized finish extinction treatment to prevent reflection laser engraving no fading
- What's Included
Ultra High Contrast
The UHC (Ultra High Contrast) broadband filter is designed to improve the visibility of various deep sky 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 with heavy light pollution.
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 Apply to 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 / 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
This filter is not for EF-S camera lens.
UHC with narrower passband provides higher contrast than CLS
- Suitable for color CCD cameras and unmodified DSLR
- UHC has a substantial red passband and offer superb views for objects like the Orion Nebula (M42)
Cleans up light pollution
base material through double sided polishing finishing grinding processing
Aviation aluminum, convenient disassembly
exclusive design of box, more better
needed to reset the focus to infinity. Works great. Helped one capture the Milky Way at a greater depth than would have been possible without it. Because it sits inside the camera body, during a trip you can carried the protective case around, so it was easy to remove and get back to touring
Important: this filters is not designed for sun observation; do not look directly into the sun with this filter; otherwise it will burn the eyes. Full Spectrum modified cameras will need an additional IR-block-filter.
