Quote:Hello,Take a look at TSAPO65Q. May be a dimmer aperture, but perfect stars and no CA edge to edge. Visit my blog to see images. http://buscandocometas.blogspot.comVicente.
Quote:I have to disagree. The author is using the scope visually, not photographically. With the Nagler and Ethos, he should be getting good stats even at the edge. Something is not right if a triplet APO is giving lots of false color at 16x and 36x respectively.
Quote:Its an F5. So i assums that causes the CA?

What some may view as an argument I view as a different perspective.
Quote:The only scopes that seem to provide a perfect fov are in the 5k region... Ie TV NP1-01
Quote:But I have an EdgeHD 8", and for the same size true field, it is as sharp as my 6" APO. Of course I can get a 2 degree true field in the 6" APO, but only a 1 degree field in the EdgeHD 8". But a stunningly good 1 degree field.
Quote:The Televue 101 was of course an excepetion, offering both a very large field and a very sharp field, but in the end was too small of an aperture to me.Fantastic though. The only small refractor that I ever liked more than a litte. I didn't use it much, but again, it was the only small refractor that I ever enjoyed using. But only under very dark skies where I could exploit its wide field capability.
Quote:Hey guys thanks for the addition feedback. I have a2in WO diaginal and so is the coorect image baader. At night both diaginals give approx the same amount of smearex edge stars. But oddly duing the day the baader with no doubt has the flatter field. Very odd and suprising.
