For the very first time we will present our filters on the other side of the atlantic ocean. We will participate at the NEAF (North Eastern Astronomy Forum) 2013, held in Suffern, NY (USA) from april 20-21.
You may find us at the booth of our largest US-reseller Oceanside Photo & Telescope (OPT). Gerd will be there to show you the quality of our products and to answer all your questions you allways wanted to ask about our filters.

We would be very happy to meet you there!
