Description
The Optolong LRGB + HSO 36 mm is a comprehensive package consisting of seven rimless astronomical filters designed specifically for professional astrophotography setups.
Each filter within the LRGB palette boasts exceptional efficiency, surpassing 95% transmission in the maximum transmission band. With high-quality glass substrates and a full multilayer coating, these filters produce images that are incredibly vivid and contrasted. Additionally, the G and R filters have been carefully designed to effectively eliminate signal interference from sodium lamp spectral lines, which are a primary source of light pollution.
The HSO palette comprises narrowband filters that excel in capturing stunning photos of emission nebulae, including the renowned Pillars of Creation. Furthermore, the narrow half-width of the Hα, S II, and O III bands enables astrophotographers to collect valuable photographic material even under challenging conditions like a full moon.
All filters included in this kit are equipped with a full multilayer anti-glare coating that is applied using advanced ion implantation techniques. This not only ensures exceptional optical performance but also enhances durability, making the filters highly resistant to scratches.
