I have a Kowa spotting scope (the TSN-2 with 77mm objective,
bought in 1987). Recently Kowa introduced a low magnification
eye-piece specially designed for digiscoping, Kowa calls it
"TSN-VA1 Photo and Video Adapter" but it is in fact a large eye-piece
with very long eye-relief (57mm) and includes a built-in adapter for
attaching cameras. It provides 8x magnification on the 77, 66 and
60 mm Kowa scopes and 8.7x on the 82mm Kowa scopes.
This works very well with the Oly c-750 [zoom lens, 6.3 -63mm,
SLR equiv. 38-380mm]. With my old 77mm Kowa
it provides an effective telephoto range from 580mm focal lenght
up to 3040mm focal lenght (ie, it is usable with the c-750 lens
focal lenght varying betwen 12mm and 63mm). One of my first photos is posted in my gallery (the bird was at about 40 ft from camera):
The camera produced file for this photo, including the EXIF, can be seen at http://www.pbase.com/dacolphotos/c750kowa77
The major drawback of the above system is that when birding one
has to change the eyepieces in order to photograph (as 8x is not what one usually uses a scope for...). Thus setting-up for a photo takes a bit longer than in traditional digiscoping.
See attached photos of the set-up.
