Optolong 2" L-eXtreme Schmalband Nebelfilter DSLR und Color Astro-Kameras


The L-eXtreme Dual Bandpass Filter enables nebula photography with extreme contrast - light pollution is no longer an issue 

  • 2" low-profile filter cell suitable for filter drawers, filter wheels - with M48x0.75 filter thread
  • The filter has a very narrow bandwidth of only 7 nm for O-III and H-Alpha and provides a very high contrast
  • The areas of light pollution are completely blocked, so successful deep-sky photography is also possible from close to the city
  • The filter is suitable for mono and color cameras
  • H-Alpha regions, but also planetary nebulae can be photographed even at full moon
  • Delivery in a stable plastic packaging 

Optolong L-eXtreme Dualband Nebula Filter for Color Cameras
The spread of cities and the associated light pollution is 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, which is often not available. 

Optolong L-eXtreme filters allow the use of color cameras such as SLR or single-shot astro cameras and thus save time and money. The filters are dual bandpass filters that have been specially developed for color cameras. The important areas where important nebulae glow, such as H-alpha and oxygen (O-III), are allowed to pass almost unhindered. The rest is blocked. The filter thus represents a real alternative to narrow-band nebula photography with MONO cameras. 

Optolong L-eXtreme filters offer even more contrast than the L-eNhance. The transmission is even narrower and only H-alpha and O-III are transmitted. The result is a harder contrast for maximum detail recognition.
