I have been aware of Digisco adapters for about 5 years now and always impressed with the craftsmanship of Yoshi Ishimaru, along with the adaptability with many Scope Camera combinations with Kowa being the main venue .
It is a great honor when Yoshi offered me and Paul Hackett Digisco samples to present and showcase along with all the great Kowa products including the new TSN-11WZ eyepiece at the Biggest Week in American Birding. http://biggestweekinamericanbirding.com/
The products that I have received from Mr Ishimaru .
1. CH-P11 Collete holder fits around the Filter thread base of the scope for support of the Eyepiece.
