SVBONY OIII 5nm Narrowband Filter 2" (W9187DC)

SVBONY SV227 OIII 5nm Narrowband Filter 2"

The SVBONY Narrowband OIII filter is designed for nebula observation allowing 5nm bandwidth of light centered on a wavelength of 500.7nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high- and low-pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere.

Features

• SVBONY 2 inch OIII-CCD 5nm Narrow-Band filter for deep sky 2" mounted; can enhances the contrast between the target and the sky; allowing you to capture high-quality images even under the urban sky; suitable for lightly polluted urban areas and relatively dim launch nebulae
• 
  5nm Extra Narrowband Filter; the Oxygen III 5nm Extra Narrowband Filter transmits a 5nm bandwidth of light that is centered at 500nm and drastically reduces other transmissions; including wavelengths of light that are responsible for light pollution
• 
  High-quality materials; the SVBONY 2" Filters are made glass import from germany that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength; or CWL
• 
  High-level manufacturing process; the filter cell is made of lightweight;strong metal and is CNC machined; sand-blasted; black anodized; and then laser engraved; the result is a super thin filter cell that will produce a clear aperture of 45mm
• 
  Powerful functionality; like all SVBONY filters that are designated as "CCD"; this OIII also blocks infrared wavelengths from 700nm to 1100nm so you don't need a separate IR-Cut filter; make your use more convenient
