Hello 

My name is Nick Aoki live in Japan.

This my first new posting. I am sorry my bad English. I apologize wrong expression.

I would like to show Bino NV with 90 degree angle position.

I attached picture and diagram. The NV is covered in with white aluminium case and attached with mirror box which has 2 silver coated mirrors.

To make Bino, Eyepiece of NV is removed and Pentax Papilio is connected with  close up lens.

I can watch objection at zenith direction very easy with amazing view.

Mount is free stop and has sensors are attached and connected with I pad. 

This product was produced by my friends in Japan.

The following products are used for this product.

Night Vision: ACT PVS-14 Photonis 4G INTENS WP

Bino: Pentax Papilio with close up lens 1.2x

Filters: H alpha 5nm,7nm Longpass 650nm, 685nm 

Tele converter: 3x 5x by Armasight 

 

The aluminium case is also use for my main scope 20 inches dob by Hubble Optics product.

 

I am happy with this products and I would like to hear your comments.

Hello,

Thank you for reading my topic. 

The system is low power equipment.

The powers are 1.2X without teleconverter. 3.6x with 3X teleconverter and 6x with 5X teleconverter.

 

Thanks,

Nick

Very nice set up. And the filter wheel makes it so much more convenient to use. smile.gif

Thank you for your comment.

It has also two mirror make not only 90 degree angle position but also erect image.

It is fun to watch constellation and DSO even in Tokyo.

 

Thanks

Nick, as far as I know, there isn’t much information on availability of Night Vision devices in Japan.

 

Can you tell us what type of availability in Japan for Night Vision and what the prices are compared to US or UK?

 

It would be nice to add that information to our resources sections in “Best of NV” pinned thread.

This system looks very elegant, compact and convenient for low power use.  With the filter wheel between the afocal 3x lens and the Envis objective, does it cause the image to vignette?  And, is the PVS 14 easily removed from the aluminum housing for use with a telescope?

We can buy ACT in Black in Japan. I think all items from ACT in Black are available in Japan.

ACT has sales representative in Japan.  Night Vision -Walker is name of store.

The following are items for astronomy and prices.

PVS-14 Photonis 4G intens WP $6570 (FOM 2000)

PVS-14 Harder Gen 3 FOM2100 P45 WP $6570

PVS-7 Photonis 4G intens WP $6750 (FOM 2000)

PVS-7 Harder Gen 3 FOM2100  $6390

The prices are cheaper than UK and other European countries due to lower consumer tax. 

Off course more expensive than US.

 

Some other item is available like a ACT DTNVG, MUN MINI-14.

 

Thanks,

Noboru

Hello Geezer Gazer,

Yes, it cause the image to vignette. The vignette level is same and when we use adapter for Envis afocal lens.

Filters case thickness are reduced to maximize FOV.

I have never take NV from aluminium case after assemble, this unit is used to connect telescope.

I attached drawing for telescope setting.

Due to heavy weight of Bino unit, NV need aluminium case to protect damage.

 

If you have any other question, please let me know.

 

Thanks,

Hamamatsu in Japan makes some very high performance image intensifier tubes, including in common form factors like the 10160. Might be worth looking into the availability of domestic NV tubes.

Thank you for your information about Hamamatsu.

I will try to find information and will exchange information in cloudy nights later.

What focal length lens did you use and what field of view/magnification do you get with the papilio?

Hello Peter,

The focal length lens of Papilio is 26mm(original eyepiece)/1.2 (Papilio + close up lens)=21.67mm

The Papilio is used as Stereo microscope. Papilio expand the image on fluorescent screen of NV.

So the field of view is as same as with original eyepiece.

Without afocal lens of field view is 40 degree. Magnification is 1.2 times.

 

I hope my explanation is what you want.

 

Thanks,

Nick

I contacted with Hamamatsu and confirm that they do not produce image intensifier for night vision anymore unfortunately.

 

Thanks,

Aoki-san, thank you for posting this very interesting information.

 

Is the product going to be made available to buy in the U.S. (without the NV device)?

 

Can you tell us what lens is used for the 1.2x close-up lens? I assume there are actually two 1.2x lenses, one for each objective. But the distance between the objectives changes when the Papilio is focused, so are the 1.2x lenses mounted to move as well?

 

Which Pentax Papilio is used, the 6.5x or the 8.5x?

 

-Bill

Hello Bill,

Thank you for your interest for 90 degree angle NV bino.

I contacted with my friend. The answer is following.

This system is hand made products. It is difficult to make system without NV(actual product). 

There are lot of kinds of NV products,so it is difficult make standard products.

 

The specifications of close up lens are followings

Aperture: 50 mm

Type: Achromatic lens

Focal length: 150 mm.

Manufacture: Siguma kouki.

The reason he chose Papilio is aperture lenses are close each other, one lens is enough.

The close up lens is fix in front of aperture of Papilio

He chose 6.5x type for me.

 

I would like to show his blog. 

http://imdiygo.la.co....jp/kobo11.html

Unfortunately, it is written in Japanese. But you may translate in English by Chrome. 

 

He produce several interesting astronomical products like 2" bino viewer, extension lens without magnification and so on.

http://imdiygo.la.co...ex-English.html

 

He is now trying to make NV color type by using bino system.

http://imdiygo.la.co...3.html#20190421

 

I would like to report when finish products.

 

Thanks,

Nick
