Baader MaxBright® II Binoviewer

#1

Post by AntennaGuy » Mon Sep 30, 2019 2:32 am

So, this new product (long awaited from Baader) sure looks interesting. Big prisms for larger field of view than other binoviewers.

I've bookmarked this as part of my plan for my ultimate telescope system. Looking forward to seeing it for sale in the USA.

Looks good, and way cheaper than their MkV model!

I presume you are aware of the guy in Croatia who "supercharges" Leica (and other) binoviewers? See https://www.cloudynights.com/user/208407-denis0007dl/ (check out his current "Classifieds" from this link)

I haven't heard anything negative about him, and he has been advertising his products on CN and IceinSpace for a number of years.

Pretty Cool. I need to get one of these for the "floating in space" effect. It would be a great addition for my 6" frac. :Astronomer1:

OK... maybe I'm just really slow today, but I'm puzzled by this particular suggestion.

I thought that was supposed to be a direct consequence of having a really wide apparent field of view. The RKE eyepieces are advertised as having a 45 deg AFOV. So.... how do they generate that floating in space effect? Is AFOV not the definitive feature?? Is it some combination of AFOV and eye relief? Something else, perhaps? In the case of a binoviewer, I presumed the effect followed simply from being able to use both eyes, so that would be different, I guess. But if using only one eye, then...?

Large AFOV means only that there is a wider AFOV than the eye can take in. So it involves a "kind of" floating in space effect since its not like looking through a window.

Whatever the RKE does is different. I have no direct experience but it is intriguing. Here are some reviews. Apparently the eye relief and some tricks of human perceptual psychology combine to give a "floating" impression. Folks seem to giggle at their use in binoviewers.

https://www.cloudynights.com/topic/4438 ... rformance/
https://www.cloudynights.com/topic/6778 ... -28mm-rke/

Some folks don't see it. Since it appears to be psychological YMMV.

The most credible explanation is that the RKE without eyecup has a bevel angled such that when they eye is at the exit pupil the eyepiece disappears.

Yes, I just saw that mentioned in a comment at one of the links.... I wonder if part of seeing or not seeing this effect may also be related to whether one is near-sighted or not! In any case, I suspect that with my older eyes I'm more interested in the clarity, brightness, contrast, etc. of the image that I can see through the eyepiece than with whether I can get that particular feeling of disassociating from the eyepiece/telescope. Thanks again for the education.

Eyepieces with larger eye lenses with thin tube walls will also show the effect to a certain degree I have heard.
The RKE is quite a common eyepiece used for sketching at the eyepiece because of the view produced and the ease of eye placement.

The Hyperwide eyepieces give you the looking out the picture window into space, the RKE view seems to "float" above the eyepiece.
