Tele Vue would like to announce a NEW Ethos Eyepiece ! a 21 mm :jump:

In the continuing development of the critically acclaimed Ethos eyepiece line, we are very proud to introduce
a 21mm focal length meeting all the performance goals set by the original 13mm.
http://www.televue.c....asp?ID=311#E21

Focal Length:  21mm
Apparent Field:  100°
Eye Relief:  15mm
Effective Field Stop Dia.: 36.2mm
Barrel Size:  2"
Weight:  2.25 lb.

The 21mm Ethos will be available December of 2009. However, you can own an original prototype this summer!
In our continuing support of Stellafane, Tele Vue has donated one of its three prototypes to Springfield Telescope Makers Inc. for auction.
See Stellafane.org for auction details. All auction proceeds will help support the birthplace of amateur telescope making here in the United States – Stellafane.
