Feature(may vary by option.)
●CLS filters with wider passage range than UHC and are therefore more suitable for reducing light pollution during mild observations
●This filter is aerometal-active CNC machining sandblasting which is useful and feels comfortable
●The filter has a multi-layer anti-reflective coating and an optical base coating that is not glued to glue to reduce virtual light as much as possible
●This filter compatible with colour CCD cameras and non-modified optical DSLR filters can effectively suppress harmful light in cities
●95% transmission of main mist emission lines 0.1% off-band transmission especially of the main emission lines for artificial light pollution

Description
The Svbony 1.25in CLS filter can block the wavelength of artificial light and improve contrast of astronomical objects. With the CLS filter, you can observe the mist in a small telescope. CLS filters are suitable for visual observation, black and white photography and colour photography of fog, galaxies and star clusters under light to moderate light pollution.
Warning: The SVBONY CLS filter is not designed for observing the sun. Do not use Svbony cls filter to observe the sun
Package contents:
1 x SVBONY 1.25 inch CLS filter
1 x durable plastic box
Clear image
- Use optical glass instead of resin material to increase light transmission
- The filter has multiple anti-reflective coatings and non-glued optical substrate coatings to minimise vignetting
- The ion-assisted separation coating ensures durability, scratch resistance and CWL stability

Compatible with 1.25 inch eyepiece You can use it for all 1.25 inch eyepieces with standard M28.5 x 0.6 mm filter threads |
Durable without deformation Precision CNC machining technology for aviation metal materials. The sandblasted black anodized finish is frosted to avoid reflections. The laser engraving will not fade. |
Storage box The plastic housing with high pressure EVA housing can protect your filter from dust and moisture |
Spectrogram
--90% transmission of main mist emission lines (d. H. Ha 656 nm, OIII 496 nm & 500 nm, SII672 nm) and H-beta 486 nm).
--0.1% off-band transmission, especially the main emission lines of artificial light pollution (i.e. Na 589 nm, Hg 435 nm and 578 nm).
--CLS filter with a wider flow range than UHC and is therefore preferred when observing
Light to moderate light pollution
