Product Description

SVBONY H-Alpha Filter 7nm for EOS-C Clip Narrowband Astronomy Telescope Monocular Photographic CCD Filter for DeepSky F9169D

Because H-Alpha is 656nm mainly through the high permeability of the spectrum, and 656nm spectrum of the color presented by the red-based, 300-1100nm cut-off depth to get the details of the launch nebula richer. Extremely narrow bandwidth allows only the 656nm band to pass through the filter, can effectively cut off the artificial light Na lamp and Hg lamp interference to make the transmission line through, so as to improve the nebula contrast. With CCD is better choice for deep sky photography and wide-field astrophotography.

Craftsmanship:

■Optical high-precision double-sided polishing to ensure that the parallelism is higher than 30 “and high flatness 1 / 4, to ensure that does not affect the image quality of the image.
■Precision double-sided optical coating, non-two-piece glue, effectively improve the transmittance and cut-off depth.
■Electron Gun Evaporation Technology (E-Beam Gun)
■Ion source assisted coating technology (IAD), to improve the density of the film to ensure that the filter wavelength to minimize the impact of temperature caused by the temperature drift.
■High uniformity planetary wheel coating fixture to improve the uniformity of the filter wavelength
■Optical equipment professional fine sandblasting and anode treatment, the box to do extinction treatment to prevent reflection
■Laser engraving LOGO-never fades
■Metal frame, superior aviation aluminum

Features:

The SVBONY CLS EOS -C Filter is suitable the Camera Type: 60D/60DA, 7D Mark II, 80D/800D, 77D/70D/760D/750D/700D 650D/600D, 550D/500D, 400D, 100D/1100D/1200D/1300D.
■High cutoff is effective the light damage and other stray light
■Clip filter design reduces internal reflection and color cast shift
■Using Germany imported glass, using double-sided polishing processing
■For the emission line 656nm transmittance of 85% or more
■The narrow-band filter, even in areas where light pollution is heavy, and the full moon (the moon’s largest and brightest) is the same, very narrow bandwidth, which reduces the interference of the external environment, but The weather is when the haze and cloudy not possible arrive it.
■Precision CNC integrated molding
■Multi-layers anti-reflection coating
■Frame with high-quality aluminum alloy material, anodized extinction treatment
■Lined with double-layer EVA damping cotton
■Carton PP environmentally friendly materials, simple and beautiful
