This innovative filter is designed to enhance deep sky nebula photography, making it possible to capture stunning images even in the face of urban light pollution. With its tight narrowband limits, it effectively blocks out unwanted glow from city lights, allowing you to focus on the celestial wonders above. Say goodbye to the frustration of light pollution and hello to breathtaking astroimages with the L-eNhance Filter.

Advanced Filter Technology and Specifications

Crafted with precision and care, the L-eNhance Filter features a multiple anti-reflective coating on the optical substrate, ensuring durability and scratch resistance. The filter's precision coating technology based on ion deposition provides stability on the CWL (central wavelength), unaffected by temperature changes. Key specifications include a filter diameter of 2 inches with a connecting thread of M28,5 x 0,6mm (Eyepiece thread 1.25 inch). The optical glass material and spectrum range from 300-1000nm, with off-band blocking exceeding 99%. The surface quality meets MIL-O-13830 standards, and the filter is finely optically polished to ensure an accurate 1/4 wavefront and highest parallelism over both surfaces.

Unmatched Performance and Versatility

The L-eNhance Filter is the perfect solution for astrophotographers looking to capture detailed astronomical images from even the brightest, heavily light-polluted areas. Its maximum transmission lines of up to 90% and narrow bandpass for wavelengths of O-III, H-Beta, and H-Alpha lines help control the impact of light pollution. This filter is not limited to expensive telescopes; it works exceptionally well with a wide range of optical instruments, including fast Newtonian telescopes, double-lens ED refractors, and achromats. Whether you're using a DSLR or color CMOS and monochrome CCD cameras, the L-eNhance Filter will deliver exceptional results, allowing you to achieve image quality that comes close to CCD monochrome cameras. Embrace the convenience and cost-effectiveness of this filter and unlock a new level of astroimaging.
