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
