Product Description

Optolong filters are here to help all of us Earth based Astronauts.  As light pollution gets worse and worse we need something in our tool kit to help us photograph the night sky.  Urban sprawl has created skies that just aren't conducive to imaging.  You can fight back with the assistance of filters.  In the past it has been an expensive proposition to purchase separate filters and filter wheels.  The Optolong L-eNhance filter is doing its best to make it  a much more simple process to improve your photography.  

The L-eNhance 2" helps us by isolating specific emission lines.  It effectively isolates nebula emission lines at OIII, H-Beta , and H-alpha while achieving a maximum transmission of up to 90%.  This Tri-Band filter has been designed to work with DSLR, Color CMOS, and monochrome CCD Cameras

Their design is quite ingenious.  It keeps the prominent RGB colors of nebula while blocking out most wavelengths of light pollution.  The color curve chart in the images will show you everything you should need.

The filter itself is very well made.  The multi-layer anit-reflection coating is based on an Ion-assisted technology known for durability and Resistance to scratching.  The technology also provides stability to the CWL (central wavelength) allowing no deviation with temperature change.  The 1/4 wavelength Schott glass filter is housed in a very thin CNC machined housing..  The L-eNhance comes in a plastic case to protect your investment when not in use.
