Filtercell-Opening tool for 1,25" cells

The Filtercell-Opening tool is a small but very useful accessory:
You can use it to open and close filter mounts very easily and without danger to the filter, e.g. if you have to clean the filter or if you want to use a different filter in the holder.

• The key fits all current versions of, Astronomik,B & W, Heliopan, Vixen, Celestron, Lumicon, Meade and Zeiss.


• It is still elastic and well useable at temperatures below 0°C


• Upon request I can make keys for other Diameters.
