Hi,
For sale is an astronomik EOS CLS Clip filter for Canon cameras.
Helps with reducing LP when shooting from light polluted areas.
From the Astronomik website
"The Astronomik CLS blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass. All the important emission lines, as well as the spectral region that the very well dark adapted eye can see, can pass through the filter."

Bought from a member in IIS here

Good condition, looking at $80 posted.
Please check the astronomik website for camera and lens compatibility.
it worked well with my 1000d for prime focus.
Selling it as I just bought a CCD camera.
