Key features
- •Full-frame compatible: the full-frame SV220 2" telescope filter is designed to fully leverage the large size of full-frame sensors; Greatly reduces the risk of vignetting in wide‑angle lenses (suitable for 2 inches)
- •Average OD5: SV220 3nm Dual-Narrowband Filter offers a wide cutoff range of 300-1050nm; its transmittance is as low as 0.001%; effectively suppressing stray light and light pollution; improving signal-to-noise ratio for more detailed images
- •Minimal halo coating design: the 3nm H-Alpha and O-III Narrowband Filter features a minimal halo coating that reduces glare; ensuring sharp; detailed imaging of celestial objects with enhanced contrast; color accuracy; and reduced light pollution
- •85%+ transmission rate: the SV220 3nm H-Alpha and O-III Narrowband Filter offers high contrast and detailed imaging; enabling fast capture of deep-sky objects even in heavily light-polluted cities
- •FWHM: the SV220 3nm Dual-Narrowband Filter's narrow bandwidth of 3±1nm can effectively filter out most of the background stray light; making the details of the target celestial object clearer; The 2-inch ultra narrowband filter has a thread specification of M48×0.75 and a barrel size of Φ50.8×7 mm
- •Broad spectral coverage: the telescope filter's cutoff wavelength range of 300-1050nm covers a broad spectral region from ultraviolet light (300nm) to near-infrared light (1050nm); making it suitable for observing a variety of celestial objects
