Hi all,
Televue has recently announced the new 3.7mm 110 degree ETHOS - SX
http://www.televue.com/engine/TV3_page.asp?id=128
3.8mm focal length is too short for me as it would give over 420X in my 14" and over 550X in my 18" . When I use those higher powers I prefer to get there by barlowing my Pentax XW's in the TV Powermate.
110 degrees is also more FOV than I am ever likely to need but I can appreciate this eyepiece will appeal to a lot of people with 6" to 8" newtonians and APO refractors who don't wear eye glasses.
Whether you like it or not. Whether you buy it or not, it is clearly cutting edge technology and a wonderful piece of engineering and optical design.
Cheers,
John B
