Product Questions

What is the in focus requirement of the binoviewer

Question by: Brian Potter on Nov 10, 2016 5:02:00 PM | 1 Answer(s)

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?

What is the total light transmission of this binoviewer?

Question by: Bruno Yporti on Jan 7, 2018 12:49:00 AM | 1 Answer(s)

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.
