Experience Optolong Ultra High Contrast Telescope Filter - 2" Holiday Cheer Edition [PiIdAyHn]

The Optolong Ultra High Contrast Telescope Filter is a cutting-edge optical accessory designed to enhance the visibility of deepsky objects in areas with heavy light pollution. This filter is engineered to selectively reduce the transmission of light pollutants, including mercury vapor lamps, sodium vapor lights, and atmospheric skyglow, resulting in a clearer and more detailed view of celestial objects.

Key Product Features and Specifications

Crafted with Schott substrate material, this UHC filter boasts a 2.0mm thickness for durability and optical clarity. It features a 60/40 surface quality and is finely polished to ensure an accurate 1/4 wavefront and <30 seconds parallelism over both surfaces. The filter has a 95% transmission of main nebula emission lines, such as H-alpha, OIII, SII, and H-beta, while blocking the majority of artificial light pollution emissions. This results in a higher contrast and more vibrant images, ideal for both visual observation and photography.

Practical Applications and Benefits

Ideal for color CCD cameras and unmodified DSLRs, the Optolong UHC filter is a must-have for urban astronomers dealing with light pollution. Its narrower pass-band provides superior contrast, making it particularly suitable for observing objects like the Orion Nebula. With its substantial red pass-band and high optical density, this filter enhances the viewing experience and captures the beauty of the night sky. Its robust construction and advanced coating technology ensure long-lasting performance, making it a valuable investment for any astronomy enthusiast.
