Thismillimeter glass F11 binoculars, I am inspired by Zhang painting, is fascinated by the mirror in the picture. So we made a prism with two 80900 refracting mirrors and a microscope. I am amazed at the sharp image of the prism. Compared with astronomical eyepiece, microscopic eyepiece has the advantages of sharpness and transparency, but the field of vision is not very wide, but for respecting classics, this is enough.

Impressive..

 I have been to Grand Canyon many times, every year for 28yrs since I live in Northern Arizona. I have seen this style scope there. Impressive you duplicated it.. Amazing how even back then they had some great optics at hand.. I will be going back next month for offering my services to show the transit of Mercury across the Sun. I will visit this room again, and maybe get some closeup shots of this historical binos there, or what may be a reproduction. Never look too close at it. I believe it was not a working unit. My remembering sadly is not as good as it use to be. Binos are my thing too, as you can see from my signature info... Any case my hat off to you for your stunning project.

Thank you very much for sharing your experience. Seeing the picture of the Grand Canyon, I was fascinated by two people in binoculars and paintings. I think they are very much like me and my wife. Although this mirror is not very similar to the imitation, I am still satisfied. Maybe I'll add a couple of eyeglasses and some upgrades in the future.

I am a bit confuse by your statement,  "is fascinated by the mirror in the picture" at top of article, and again above (although this mirror)?  Are you referring to the (telescope) as mirror or something else?

I suspect it's just a translation artifact.  Try going to a Japanese or Chinese site and use a Chrome browser or Google Translate.  You get some odd translations of idiomatic phrases.

That binocular telescope in the postcard is an early Zeiss is it not?

Thank you for your question. This is really the job of translation software. Mirrors refer to my binoculars.

Some new Olympus eyeglasses have been purchased. These small eyeglasses have very small field of vision, but they can provide sharp and low color aberration imaging, and have flat field effect. I also purchased two Carl Zeiss eyeglasses, which were supposed to be made in the 1970s. The glass is not coated, and I hope to have a sharp imaging performance as well.

Those eyepieces look like microscope eyepieces.  I use a Zeiss microscope binocular head with many different microscope eyepiece pairs and the work very well.  Very nice telescope you have made!

Hello, thank you for your compliment. This is really a microscopic eyepiece. Occasionally, I use a microscopic eyepiece on an astronomical telescope and get good results. I think these microscopes should be very good at observing planets. It has simple structure, flat field effect and sharp imaging.

But the only drawback is that the field of vision is very narrow.
