Hi all, I've read much of the benefits of binoviewers and am convinced they are a great upgrade. However, I also hear much about how good high end (Televue) eyepieces are. As it turns out, you can get a Televue DeLite for about the same as an entry level binoviewer (~$250). I recently had the chance to look through an Ethos and the view was impressive.
For those who have tried both: if you had to choose between entry level binoviewers with some budget-friendly eyepieces like the Meade HD-60 line, vs. a Televue eyepiece like the DeLite, which would you rather have? Assume that this is for narrow-field views like planets or globulars and you can't have both.
If possible, you should try binoviewing before buying.... It does not suit everyone. For me viewing planets, Moon, globulars and brighter DSOs with both eyes is far better than single eyepiece views.
I can view for much longer periods with two eyes than with one without any eye strain.
The actual visible difference in most binoviewers is not as big as the prices would suggest. The price is more an indication of the robustness of the build than actual visual quality.
The more expensive ones do allow the use of wider view eyepieces due to their larger clear apertures but for planetary viewing that is never going to be an issue.
The best eyepieces for binoviewing planets are things like that Tak Abbe series, which show finer detail than Ethos, Delite etc. After owning Ethos, Delos, DeLite, Nagler, Radian, Panoptic, XW, XF and LVW wide fields, I think the XW and Delos are the pick of them, unfortunately the sliding eyecup does not suit binoviewing and removing the eyecup leaves the eye lens very exposed...
The main negative about binoviewers is that they do have avery noticeable effect on the brightness of the view or lack thereof... the ultimate solution is a binoscope but that can lead to a very light wallet...
