I love this bino.

I also shudder to think how many $ are in that photo, but I can admire it all the same. I'm doing a similar thing, have bought all the same bits (OK, Surplus Shed not APM) including the Ethos 17mm, 3" focusers etc but haven't found the the courage to buy the Matsumoto bits.

 

Not yet at least.

 

:bow:

There is quite a lot...But I intend to build it as an all-rounder, so consider it a lump sum investment, and after that I'm done with instruments.

Oh c'mon!!!!!

You need a 16" bino as well!

I agree with Jonathan. You need a 16", and then you could use these as the finder scope. Seriously, that is one gorgeous binoscope. I am jealous.  :bow:

Funny you should mention it; one option I'm considering on Sterope is a flip mirror that insets into the beam to switch the eyepieces from the primaries to a binocular finder. Maybe even a 127mm finder...

Nice looking design. I've been happy with my Matsumoto EMS units.

Added a silver plate, these symbols are not intended to be brand logos, they are just meant to be indications of the parts which constitutes this binoscope.

Add a serial number and then go commercial with this product line! ;)

Only if I have 100 orders at hand. :lol:

To use Markus's remarks, they won't sell.

Eyepiece tfov simulation and comparision of tfov @40x.

You can see the Lzos with 17mm Ethos yields larger tfov at the same time larger afov comparing with other ready-made binoculars at approximate magnifications.

Added another plate indicating the objective lens configuration, this time made of solid gold.

Hereto the making of this binoscope itself has come to an end.

The form factors regarding 2 scopes, the other one is 100ed apo for reference:

Range88,

I admire the superb optical train and nice bling of this instrument. Looking at the components the multinational pedigree is interesting!

I assume its intended use is for visual-only terrestrial and 'rich field' star sweeping as well as being a sculptural work of art. For more demanding astronomical use I would respectfully question the compact mount which is bound to compromise high resolution use and the lack of provision for digital imaging.

FWIW I planned a 6" TMB F8 APO bino folded (2 reflections) into a compact drum-shaped OTA back in the early Noughties, with adjustable final mirror in each optical system as an alternative to a Matsumoto EMS back end. The plan was to mount it on a very simple stiff Dob mount - the drum-shaped OTA comprising the altitude axis. I sourced the objectives and schemed the optical layout. As the CCD then CMOS digital imaging revolution unfolded I gradually realised the limitations of the small aperture and limited transmissivity of this kind of instrument. It was never completed and I eventually sold the objectives to buy premium reflectors instead. Now I focus on refined Newtonians and corrected prime focus reflectors. In chasing the ultimate Earth-based planetary images I decided that these represent the 'research front' and that in this area I can achieve far more for a given investment of time.

Enjoy!

 

Tony

Hi Tony,

 

There is a field binoscopes are irreplaceable, i.e., rich field low power observation, and at that field this binoscope aims. 

Yes, this instruments are visual only, the video head can hold up to 300x with no tracking issues at all.

I recall there was one Japanese DIYer who made a TMB 152 F8 binoscope, the result was astonishing though the design is not folded. You can easily find it on Mr. Matsumoto's website.

Applying folded design will inevitably compromise the optical quality of a premium scope, I find that hard to justify buying a premium scope at the first place, let alone two.

All I can say is WOW!  great project very nice.  The picture of the 4 binos together is very cool.

The eyepieces have been got together thanks to the great TV sale.

I use Ethos series exclusively, I do find they are the best match for a binoscope.
