A small but very useful adapter:
Use your Astronomik EOS Clip-Filter with all your eyepieces! The new EOS-Clip-to-M48 Adapter accepts your Clip-filters and offers you the standard M48 thread for 2" filters: Clip-your filter into the adapter and use it with all eyepieces, prisms, mirrors or reducing adapters from 2" to 1,25".
For a very small investment you get a vast range of applications for your Astronomik Clip-Filters.
