2 years old, hardly ever used. In mint condition.
Purchased to use with a Canon EOS 500D. The Astronomik H-alpha filter is a narrow band emission-line filter for CCD photography. The filter lets the H-alpha light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive. You can read all about it on the Astronomik or Bintel website.

I've sold all my other astro equipment and certainly dont need this hanging around the house.

Brand new at Bintel $289 plus postage
My price $200 plus postage

As i said hardly ever used and in mint condition
