Ethos 8mm!!!!!!

[du900ss]

Pour info...............

 

Comme chaque année nous sommes au NEAF (North East Astronomy Forum) près de New York. Ouvert depuis quelques minutes le forum donne sa première surprise... la sortie pour juillet/août du nouvel Ethos 8mm 100°! Le petit frère du 13mm va faire des ravages. En comparaison du Zoom 8-24mm Televue il offre la focale la plus petite... et 83% du champ de la focale de 24mm!

 

At NEAF 2008 we are pleased to demonstrate a new 8mm focal length, 100° AFOV Ethos eyepiece. In addition to matching all the key performance criteria of its 13mm sibling, the new 8mm version is parfocal in 1¼" focusers with Radians, Plössls, Type 6 Naglers and 1¼" Panoptics. Further, its lighter weight and smaller diameter than the 13mm Ethos makes the 8mm suitable for anyone using a binocular viewer. Another application is for spotting scope set-ups with the Tele Vue 60° 1¼" diagonal. In comparing it to our 8–24mm Zoom eyepiece, the 8mm Ethos has the power of the 8mm Zoom and 83% of the field of the 24mm setting!
