The NGS1 (LPS-D3) is an advanced light pollution suppression filter that performs exceptionally well in both urban and rural settings. It effectively reduces interference from both artificial lights and natural night glow, enhancing the clarity and contrast of deep-sky objects.
As the world’s first filter to suppress both man-made light and night glow interference in the green, orange, and red ranges—including OI (557.7nm, 630.0nm, 636.4nm) and NaI (589.0nm, 589.6nm)—the NGS1 significantly improves image quality. It is also a successor to the IDAS light pollution cut filters, making it effective against white LED lights, as well as low- and high-pressure sodium lamp pollution.
Designed to maximize the transmission of light from emission nebulae, comet comae, and ionized comet tails, the NGS1 is optimized for longer wavelengths. This shift in transmittance range allows for better performance when dealing with oblique incidences, which are common with thin-film interference filters.
When used with lenses that have an aperture of f/2 or faster, the NGS1 effectively captures nebular emission lines, improving deep-sky and cometary imaging under challenging conditions.
