Kowa TD-1 was made a few years ago, but I guess because it wasn't as
big or as powerful, or as sharp? as what digiscopers were able to
produce with separate scope and camera units, it never caught on. It
may still be available used if not new (I have no idea). I do not
have any financial interest in this item, merely providing info for
those who might be interested in it. Angus Wilson's 2005 review:
