Optolong 2" L-eNhance Nebula Filter for DSLR and Color Astro Cameras

The L-eNhance dual bandpass filter allows nebula photography with colour cameras and reduces light pollution significantly.

♦ The filter allows images close to the quality of mono cameras with narrow band filters.

♦ H-alpha, H-beta and O-III are allowed to pass almost unhindered

♦ The areas of light pollution are blocked, so successful deep sky photography is also possible from close to the city.

♦ The striking nebula colors (RGB) are best preserved for a natural impression.

 

Optolong 2" L-eNhance dual-band Nebula Filter for Color Cameras

The spread of cities and the associated light pollution are becoming a growing problem for astrophotographers. A possible solution is the use of MONO/SW cameras and narrow-band nebula filters. This is expensive and costs valuable exposure time that you often don´t have.


Optolong L-eNhance filters allow the use of color cameras such as SLRs or single-shot astro cameras, saving time and money. The filters are dual bandpass filters specially developed for color cameras. The important areas in which nebulae glow, such as H-alpha, H-beta and oxygen (O-III), are let through almost unhindered. The rest is blocked. The filter is a real alternative to narrow-band nebula photography with MONO cameras. The natural colour of the nebula is preserved in the best possible way. The results are astrophotographic results reminiscent of working in the dark high mountains.
