Description
Optolong LRGB & HSO 2" Filter Set - Professional Astrophotography Filters
The Optolong LRGB & HSO 2" Filter Set is a complete collection of seven high-performance astronomical filters, meticulously crafted for professional astrophotographers seeking unparalleled image quality. This set is an essential addition to any advanced astrophotography setup.
Exceptional Image Quality with LRGB Filters
Our LRGB filters are engineered for maximum efficiency, achieving over 95% transmission in their peak bands. Made from high-quality Schott glass and equipped with a comprehensive multilayer coating, these filters deliver vibrant, high-contrast images. The design of the G and R filters includes specific separation peaks that minimize interference from sodium lamp emissions, a common source of light pollution.
Capture Emission Nebulae with HSO Narrowband Filters
The HSO narrowband filters in this set are perfect for photographing spectacular emission nebulae, such as the iconic Pillars of Creation. These filters offer narrow half-widths for the Hα, S II, and O III bands, allowing astrophotographers to capture breathtaking images even under challenging conditions like a full moon.
Durability and Advanced Coating Technology
All filters in the Optolong LRGB & HSO 2" set feature a robust, scratch-resistant full multilayer anti-glare coating, applied using cutting-edge ion implantation techniques. This ensures both optical clarity and long-term durability.
