Description: OPTOLONG 1.25" L-eNhance Filter Dual-band Pass Filter Designed for DSLR CCD Control from Light Polluted Skies Amateurs The relentless spread of urbanization and its associated light pollution have become a growing problem for all amateurs and astro photographers. The current solutions to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel. L-eNhance provides an economical and practical solution for amateurs. It is a dual-band pass filter which has been designed for DSLR (digital SLR), color CMOS and CCD cameras. The convenience and cost effectiveness of this filter allows amateurs to image a rich selection of astronomical images, even in bright, heavily light-polluted areas. Optolong believes the design of our L-eNhance filter is a technical innovation among filters. It effectively isolates the H-Alpha, H-Beta, and Oxygen III nebula emission lines and achieves a maximum transmission of up to 90%. The performance of this filter delivers images that superbly control the impact from light polluted skies. L-eNhance Filter Spectrum Curve: According to the characteristics of celestial body emission lines and feature of light pollution span of spectrum, Optolong specially designed and optimized dual-band L-eNhance filter in order to retain the prominent color of nebula RGB while blocking out most of light pollution. Technical Data: Substrate: B270 Thickness: 1.85mm Tpeak: T>90% Blocking range: 300-1000nm Blocking depth: light pollution line blocking >99% Surface quality: 60/40 Transmitted Wavefront RMS: λ/4 Parallelism (arcsec): 30s Package Includes: OPTOLONG1.25"L-eNhance Filter OPTOLONG 2" L-eNhance Filter Dual-band Pass Filter Designed for DSLR CCD Control from Light Polluted Skies Amateurs The relentless spread of urbanization and its associated light pollution have become a growing problem for all amateurs and astro photographers.
