Description

L-eNhance filter for deep-sky fog photography from the city
The steady spread of cities and the associated light pollution from more and more artificial light sources have become a growing problem for all astrophotographers. Common solutions to this can be expensive and include the purchase of a monochrome camera, various types of narrowband filters, and a filter wheel. Especially with inexpensive Newtonian telescopes, double-lens ED refractors or even achromatic lenses, the L-eNhance filters open up completely new possibilities for taking high-quality astronomical photos, even from the bright city. CMOS cameras can even deliver images almost like monochrome cameras. This new generation of filters makes it possible to take amazing astrophotos directly from the city with all its artificial light sources. The narrow-band passage for the wavelengths of O-III, H-Beta and H-Alpha and the almost complete attenuation of the interfering light sources make this possible in the first place.

L-eNhance description
L-eNhance offers an economical and practical solution for astrophotographers. It is a three-band pass filter designed for DSLR (digital single-lens reflex camera), color CMOS and monochrome CCD cameras. The ease of use and cost-effectiveness of this filter allows amateurs to capture a wide range of astronomical images, even in bright, heavily light-polluted areas. We believe that the design of our L-eNhance filter represents a technical innovation among filters. It effectively isolates the H-Alpha, H-Beta and Oxygen-III fog emission lines and achieves a maximum transmission of up to 90%. The performance of this filter delivers images that would otherwise not be possible due to the negative influence of the light-polluted sky.

Main application and performance
This new generation of filters makes it possible to take amazing astrophotos directly from the city with all its artificial light sources. The narrow-band passage for the wavelengths of O-III, H-Beta and H-Alpha and the almost complete attenuation of the interfering light sources require neither very large nor extremely expensive telescopes. No, especially with inexpensive mirror telescopes, two-lens ED refractors or even achromatic lenses, completely new possibilities for creating high-class astronomical recordings arise in connection with these filters. In addition, with the help of these filters, the CMOS color cameras can also deliver an image quality that comes close to that of CCD monochrome cameras.

WARNING: These nebulae filters are not suitable for solar observation. DO NOT LOOK AT THE SUN WITH THIS FILTER. You will go BLIND if you don't heed this warning.

Coating technology
The L-eNhance filter has multiple anti-reflective coating on the optical substrate. The L-eNhance filter uses a precision coating based on ion deposition coating technology. This ensures durability and scratch resistance as well as stability on the CWL (central wavelength), which is not affected by temperature changes. Absolute precision and homogeneity of the coatings as well as maximum values ​​for the transmission in the passband and the optical density in the off-band area are guaranteed for all filters.
