ngc4565 Δημοσιεύτηκε Απρίλιος 27, 2008 Δημοσιεύτηκε Απρίλιος 27, 2008 I just learned that a new Televue 8mm ETHOS eyepiece was unveiled at Neaf. I believe is will be called the new Ethos GR8 Here is what Televue said: 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! Apparent field: 100°Focal length: 8mmEffective field stop diameter: 13.9mmEye relief: 15mm (accepts DIOPTRX eyesight astigmatism corrector)Barrel size: 2"/1¼"Black barrel diameter: 53.4mmWeight: 0.95 lbs (15.2 oz.)Availability: July 2008 8mm Ethos on Binoviewer Φιλικά, Frank http://www.oaog.ca/ http://www.rascmontreal.org/ "Imagination is more important than Knowledge"
Fred Ley Δημοσιεύτηκε Απρίλιος 27, 2008 Δημοσιεύτηκε Απρίλιος 27, 2008 Hi Frank, Yeah, Al keeps churning out new eyepieces. What else can he do. At least they are all quality items and gives us an great excuse to dig deeper into our wallets. The new 13mm Ethos sounds like it is something that I would like to look through on a 20-inch dob while viewing a globular star cluster or some galaxies. Years ago I viewed M13 and M31 through an original 13mm Nagler on a 24-inch scope. The view blew your socks off.The new 8mm must be great too. I am curious as to how the Moon will look through this one. Probably similar to the Apollo film footage taken from lunar orbit. So, when do you take delivery of your two 8mm GR8's (Great)'s? -Fred www.instrumentsoflight.com - www.ras.org.ukwww.avastronomyclub.org - www.aavso.org (LEF)www.imca.cc (#9181)www.alpo-astronomy.orgAstrovox Member #4.Doing astronomy since 1970Sky & Tel subscriber since 1971www.highdeserttelescopes.com
