Sky & Tel Hot Product 2009At NEAF 2008, Tele Vue was pleased to demonstrate a new 8mm focal length, 100 degree AFOV Ethos telescope eyepiece. In addition to matching all the key performance criteria of its 13mm sibling, this 8mm Tele Vue Ethos Telescope Eyepiece is parfocal in 1.25-inch focusers with Radians, Plossls, Type 6 Naglers and 1.25-inch Panoptics. Further, its lighter weight and smaller diameter than the 13mm Ethos makes the 8mm suitable for anyone using a binocular viewer.

I am considering the 13mm Ethos for a Meade EXT-LS, can this scope safely support the weight of this lens?
The mount of the ETX-LS can handle the weight of the 13mm Ethos eyepiece.
