SV260: High Light Transmission Filter

High Light Transmission Filter: Nebula Details Right Before Your Eyes

The light transmission of astronomical filters is crucial for astrophotography, particularly in star field photography. This is because astronomical observation often takes place in low-light environments, and if the filter’s transmission rate is not high, it can result in reduced brightness of celestial objects. Only filters with high light transmission can preserve the light from these objects, capturing natural, complete images of the celestial bodies.

Therefore, high light transmission has always been one of the key indicators of filter quality. SVBONY’s SV260 star field filter is designed to provide high-quality optical accessories—so how does its light transmission perform? Let’s take a look, star field photography enthusiasts!

SII-OIII-SII Band Average Transmission Above 85%, Peak Above 90%

The SVBONY SV260 star field filter efficiently transmits light emitted from nebulae, especially in specific wavelengths. Its transmission in the SII (672.4 nm and 671.6 nm) and OIII (495.9 nm and 500.7 nm) bands exceeds 85%, with peaks above 90%. This allows most of the target light to pass through, minimizing light loss and helping you capture rich, detailed layers of nebulae.

Displaying Celestial Colors, Enhancing the Stargazing Experience

The SVBONY SV260 star field filter allows light of specific wavelengths to pass through while blocking other wavelengths, such as yellow light from light pollution and scattered atmospheric light. This makes emission lines in supernova remnants more prominent, helping you observe the edges, structure, and gas flows within nebulae more clearly.

High-Quality Optical Glass, Reducing Chromatic Aberration and Distortion.

The SVBONY SV260 star field filter is made from high-quality optical glass, ensuring high light transmission and allowing more light to pass through. At the same time, high-quality optical glass helps the filter accurately display celestial colors, preventing color deviations and distortions caused by the material of the glass itself.
