Light pollution filter for sale (and help the NHS!)

One of our Members has a redundant filter for radically reducing light pollution. It clips over the chip inside the camera. It is an Astronomik EOS XL Clip Filter CLS. The filter is for full frame Canon EOS cameras only. Full details and a list of compatible cameras can be found here: www.astronomik.com/en/clip-filter/clip-filter-fur-canon-vollformat.html .

It cost the seller about €200 a few years ago, but as this is rather a niche product, if anyone wants to buy it they can choose their own price and our Member will donate the entire proceeds to an NHS charity. Interested? Then please click on the 'Contact Us' button at the top-right of this page and we will put you in touch with the seller.
