Description
Optolong LRGB + HSO 1.25" Astronomical Filter Set for Professional Astrophotography
Discover the ultimate toolkit for astrophotographers with the Optolong LRGB + HSO 1.25" Filter Set. This comprehensive collection of seven high-performance filters is meticulously designed to meet the rigorous demands of professional astrophotography, ensuring you capture the universe with stunning clarity and detail.
Exceptional LRGB Performance
Each filter in the LRGB palette offers outstanding transmission efficiency, exceeding 95% in the maximum transmission band. These filters are crafted from premium Schott glass substrates and feature a full multilayer coating, which delivers vibrant, high-contrast images. The strategically chosen peaks for the G and R filters also effectively suppress sodium lamp spectral lines, a common source of light pollution.
Dramatic HSO Narrowband Imaging
The HSO palette includes narrowband filters that are ideal for photographing emission nebulae, such as the iconic Pillars of Creation. The narrow half-width of the Hα, S II, and O III bands allows you to capture breathtaking images even in challenging conditions, such as during a full moon.
Durable and Reliable
All filters in this set are protected by a robust, scratch-resistant full multilayer anti-glare coating, achieved through advanced ion implantation techniques. This not only ensures exceptional optical performance but also guarantees long-lasting durability.
Key Features of the Optolong LRGB + HSO 1.25" Filter Set:
- Premium LRGB and HSO filters made of high-quality glass from the renowned Schott company.
- Full multilayer coating to eliminate glare and protect against scratches.
