SVBONY 2" OIII Deep Space Filter (W9121B)

SVBONY 2" OIII Deep Space Filter

• SVBONY 2 inch OIII-CCD 7nm 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
• 7nm Extra Narrowband Filter;The Oxygen III 7nm Extra Narrowband Filter transmits a 7nm 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
