What is the in focus requirement of the binoviewer

Good evening, I just bought a Mark V. The two rings left side solidarity, it is not possible to adjust the diopter on this side? Is this normal?
In addition, on the right side, there is a small opening about 15 ° at the bottom of the right eyepiece tube. A little external light penetrates into the right tube. Is that also normal?

I like to buy a Mark V Großfeld (Giant)-Binocular. With the Bino I like to buy a Glasspathcorrector.
I am using a Takahashi 120 refractor (TSA-120) F/7.5. Would Glasspathcorrector Factor 2,6 be a good choice?
Also, I like to ask you for what Diagonal to chose for this Bino. I have the Baader 2" ClickLock Diagonal Mirror # 2956100, for a year and I am very, very pleased with it!!
Should I choose this diagonal # 2956100, or should I chose Baader 2" ClickLock Diagonal Mirror M68 thread (Zeiss) # 2956100Z for the Mark V Großfeld (Giant)-Binocular with Glasspathcorrector Factor 2,6 ?

I am interested in purchasing this Binoviewer. I have just purchased the Celestron CPC Deluxe 9.25 Edge HD. I have also purchased a pair of Mark 4 Zoom Eyepieces and the Baader 2 inch "Clicklock" that attaches to my visual back of the 9.25 Edge HD. Can you please advice me on what else I may need to purchase to connect this Binoviewer to my new SCT?
Thank you

The Mark V Giant Bino comes with a T-2-quickchanger.
If your telescope is equipped with a standard 2" clamp, we recommend
Baader T-2 Stardiagonal (Zeiss) Prism with BBHS ® coating (T-2 part #01B) # 2456095
plus
Baader 2" / T-2 Nose Piece and Camera adapter (T-2 part #16) # 2408150

The prism gives you a sufficiently wide free aperture for the binoviewer combined with a very short optical length, so that you'll be as close as possible to the backfocus distance for which the telescope is designed. The nosepiece is required to attach the star diagonal to the telescope's eyepiece clamp.

The glasspath correctors
Glasspathcorrector 1:1,25 for Baader-Binoviewer with Zeiss ring dovetail (MaxBright® II and Mark V) # 2456314Z
Glasspathcorrector 1:1,70 for Baader-Binoviewer with Zeiss ring dovetail (MaxBright® II and Mark V) # 2456316Z
Glasspathcorrector 1:2,60 for Baader-Binoviewer with Zeiss ring dovetail (MaxBright® II and Mark V) # 2456317
are optional for a telescope with f/10, but they provide additional magnifications and move the focus further away from the back of the telescope.

Is a glasspath corrector necessary for use on an SCT to correct color? I plan to use a Mark V on a Celestron 14 and do not want to add more focal length and higher power than the C14 already has. Thankyou for the answer.

What is the total light transmission of this binoviewer?

Please excuse, there is no answer to this question. What do you mean by "total light transmission"? The incoming light is split into two channels - evidently the light in both channels appears to be notably dimmer when you close one eye at a time and try to judge the brightness in each channel separately. What does not come into play during such kind of "fake-evaluation" is "the power of the human brain".
It happens "in the brain" that both light trains become reunified. And what actually happens there is that the image all of a sudden does NOT look dimmer but that fine detail and most subtle color differences within planetary surfaces become recognizable much easier and that observation happens effortlessly without fatigue - even when observing over a long time. Regardless of light throughput - the real virtue of a binocular viewer does lie in the optical quality of the glass and utmost care in optical surface polish, in perfect angle orthogonality of each prism, an immaculate beam splitter quality, highest degree of optical adjustment of all optical elements at any interpupillary distance - and only lastly: utmost coating quality. These are the most necessary criteria (in this order) for supporting an undeteriorated viewing experience with both eyes - even at highest magnification work. So - whatever anyone else is claiming - the Mark V has the best light throughput and the highest quality prism surfaces and adjustment - and and and - of any commercial astro-binocular viewer in the market.

Differences between MaxBright II and Mark V Großfeld (Giant) Binocular

In our Forum post on the german website www.astronomie.de a question was asked about the difference between the Baader MaxBright® II Binoviewer incl. case (#2456460, € 425,-) and the Mark V Großfeld (Giant)-Binocular (#2456410 , € 1425) . We have provided a detailed answer to this question, which we do not want to withhold from all other customers who do not have an account in the Astronomie.de forum. Many experiences have been incorporated into the development of the MaxBright® II Binoviewer, so that the differences are surprisingly small. The Mark V Großfeld (Giant) Binocular is produced strictly according to Zeiss specifications by the same suppliers exclusively in Germany who had already supplied Carl Zeiss Jena. For the MaxBright® II, design, development, final assembly and quality control have been and still are carried out in-house. The assemblies and individual parts, however, are put out to tender worldwide and supplied by various suppliers in Europe and the Far East. This is done, among other things, out of self-protection in order not to transfer all knowledge (all design details) to a single supplier. The Mark V offers the last percent more quality, not least due to the larger prisms, which together with the production in Germany pushes...
