The New Kowa TSN-TE-11WZ /25/60 Wide Zoom eyepiece has arrived!

I have the pleasure to announce the Kowa TSN-TE-11Z wide angle eyepiece has arrived.
Here are the Specs for the eyepiece.



Magnification:  25~60 ZOOM

Real field of view:  2.4~1.32

Exit pupil:   3.5~1.5mm (TSN-880)
                  3.1~1.3mm(TSN-770)

Relative Brightness:  12.4~2.2 (TSN-880)
                                 9.5~1.6 (TSN-770)

            Eye Relief:  17.0mm 

 Field of view at 1,000m/yds  42~23m/yds

Length: 111.mm (4.37in)

Weight: 370g (13.0oz)

Being out in the field with this wonderful eyepiece has been an incredible Digiscoping experience.
The Primary Camera I have been using is the Sony RX-100 with the 25/60.

The first day of my outing I had a chance on some Ruby Crowned Kinglets with a  Low shutter Speed due to the overcast conditions .




 Edge softness with this eyepiece is virtually eliminated which was an issue in the past with other  eyepiece models ,,it has a much more flatter field of view.

The next outing I tested the TSN-TE-11WZ on some Belted Kingfishers at a bit of a distance about 60 feet ,,so I utilized the Zoom to about 40x in which I still kept the detail and Sharpness which really was impressive,

Here are some various captures with the  Kowa TSN-TE-11WZ ,,,Song Sparrows ,,American Robin,, Red Tailed Hawk,,,The Song Sparrow Portrait close up was at 40xpower.






This Eyepiece in my mind for Digiscoping along with viewing is a wonderful new item from the Kowa lineup , and I expect it to be a big favorite which is certainly one of mine ,,it definitely gets a 10 star rating.
