Like the name of the post reads, It would be nice to know what binoculars, without restriction in price or size you'd like to own.




Canon IS 15x50. Of all possible instruments I could buy, it's probably the one that would open most new options. But it's currently selling for 2X the price where I would be willing to consider it seriously, and 3X the price where buying it would be a no-brainer.

I would also love to buy an instrument that as far as I can tell doesn't exist at all -- the optical equivalent of a Kunming 15x70, but with eyepieces and an IPD that make it possible for me to use it.

I'd love to own an observatory in a rural area with a pair of the Fuji 25x150s. M42 under a dark sky must be incredible with those things.

Handheld, I have my favourites already in the shape of a Fuji 10x50 fmt and a NIKON 12x50 se.

under dark enough skies, almost any binocular would be better than what we have with our/most of our, LP skies

What binocular would I like to own?It would also be the bin I would own and if I could only have one in my collection.It would have to be the Swarovski EL 8.5x42 SwaroVision.I tried one once and have been smitten ever since.Unfortunately I doubt if I could ever afford one.

My first choice is the 10x42 Swarovision.

But my next choice would be a hypothetical 14x70 Fujinon FMT that is a scaled up version of the 10x50, with a wide apparent field and long eye relief.

I've also wanted the fujinon 150mm D/N, but to use it with Docter 12.5 mm UWA Eps, something like a 60x150ED

Yes, or a true widefield 7x50 with a 10 degree field like the mark 41.

The Docter Aspectem 40x80ED would be the next binoculars I would like to own. On a regular basis though, I have a problem using the binoculars that I have now.

the bino's i created are my favourite.2 x skywatcher 6 inch refractors,with baader prism diagonals.the images it produces with denkmeir d14 eyepieces is nearly the equal of my doctor aspectums.but the doc's produce perfect colour free images,where as the skywatchers show some colour.

why limit the unrealistic?

a few years ago I say a photo of tow D&G 6" scopes mounted as a BT at the WSP,
but I would rather have two 6" Taks

The problem with making a Binocular telescope with the NP-101s would be dealing the the rear elements. The distance from the rear Petzval to the focal plane is very short and with a 4 inch tube, some sort of staggered arrangement is necessary. It might be possible to find a way to fit it all together with a reduced tube diameter after a 90 degree mirror, depending on the size of the rear elements.

Hi Jon,

It depends on how you make the binoscope.
There are interesting binoscopes out there with Televue 101/127/140 using Matsumoto-san EMS visual back.

Televue 140 (this must be one of a kind :

Those are very interesting. Do you know more about the EMS-L optics?

Back to OP's question, Miyauchi Binon 5x32 or 2nd choice 7x50. "state of the art" wide field handheld. Of these two, I think the 5x would be more distinct in the views offered especially under dark skies, compared to a good 10x handheld.

Hi Jon,

Yes, I studied Matssumoto-san EMS work. I think EMS-L is now EMS-UL (Ultimate L, silver coated mirror).

Light path is 150mm, image circle 38mm. I forgot mirror size but I believe newer version has large enough to deal with f/5 light cone.

He has good introduction written in English:
