SV260: High Light Transmission Filter

SV260: High Light Transmission Filter

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. Read More

Differences Between Narrowband Filters, Broadband Filters, and Multiband Filters: SV220, SV260, and SV240

Differences Between Narrowband Filters, Broadband Filters, and Multiband Filters: SV220, SV260, and SV240

How to Choose Between SV220, SV240, and SV260 Filters. SV220 Targets specific wavelengths near OIII (500.7 nm) and Hα (656.3 nm), enhancing signal capture from nebulae while reducing sky background brightness. SV240 is esigned for urban areas with significant light pollution, suitable for photographing galaxies and reflection nebulae. SV260 ois effective for capturing images of various celestial bodies, including galaxies and star cluster. Read More
