balancing sensitivity and resolution for both planetary and extended exposure imaging

The Antlia LRGB V-series PRO Filter 50mm highlight both the spectral gap design between green and red filters to minimize effect of light pollution and high transmittance of useful emission lines which means it remains effective for weaker emission lines from galaxies and nebulae

Quantum Efficiency: High QE for exceptional light capture

Optolong CLS Filters Telescope Mounting Clamp balancing sensitivity and resolution forThe Optolong CLS (City Light Suppression) broadband filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i. e. skyglow). Together with the highly
