Whats about binoviewer and high resolution?

Hi at all,
whats you think about observation trough a binoviewer in planetary view ?
There is gain or not ,due the prism,more optical surface ecc... don't worth
the price ?
Thanks

Hi:

Oh, there's "gain." But the gain is due to a binoviewer allowing you to use
both eyes. It's a more relaxed and "normal" way to view. On the planets, a
binoviewer is hard to beat. Not only is it more comfortable to use, using a
binoviewer reduces the prominence of floaters in your eyes at high power. I can
always see more planetary detail with a binoviewer, even when using fairly
inexpensive eyepieces with one.

On the deepsky? A good binoviewer can still be amazing. Yes, the image is a
little dimmer than with a single eyepiece (depending, of course, on the quality
of your binoviewer), but I can still make out more detail on many objects
"with" than "without".

One additional "benefit" of a binoviewer is that it delivers an amazingly
attractive pseudo-3D effect both on planets and deep sky objects. Observing
M42, for example, some stars appear to be in the distant background, while some
are in the foreground. Of course, this is just your brain fooling itself into
thinking that it MUST be seeing depth since it's seeing with two eyes--the
baseline between your two eyes doesn't even begin to allow for true 3D even on
the Moon, of course--but it's an attractive and seductive effect nonetheless.

I RARELY observe visually without the Denkmeier any more.

If you're interested, I have a review of the Denkmeier Standard posted at
http://www.cloudynights.com/accessories2/denkmeier.htm. Within the text of
this review, you'll find a link to my earlier review of the Denkmeier 2 inch.

Ditto for me. Rod covered it exactly as I would have. Nothing can beat
sitting in a good oberving chair with a tracking scope equipped with a pair
of binoviewers. I will spend hours at a time looking at one object. Only
thing I could think to add is a cupholder.

Clear skies,

My experience has been that resolution tends to improve, but sharpness tends
to get worse becaue of the added mirror layers as well as induced
chromatic abberation with binoviewers that use more prisms than necessary.
I've think I've only looked through a Denkmeier once (and only at low power),
so can't comment on the high quality binoviewers. I suspect the high
quality binoviewers eliminate this problem though.
Low quality binoviewers can be good for solar and lunar observing. High
quality binoviewers are probably good for deep sky and planetary viewing.
Although if you want to get the most sharpness out of planetary viewing,
then I'd stay away from them in general (unless you're the type of person
that tends to find more detail because they use two eyes).
You get what you pay for, and if possible, try before you buy...

Hi Eric,

No offense intended but you don't have any experience with binoviewers.

Regards,

Steve

You mean you don't have one?! :-)
