Optics do not start from the US even if they machine their own optics like Astro-Physics, TEC, TeleVue, and now Stellarvue also.

Sorry, I'm not sure I understood you correctly.

 

Agema Optics is USA company as well as TEC as well as AP and TV.

That is true.  These are USA companies that make their own optics.  But FIRST they buy the glass blanks.  That is usually from Ohara in Japan.   Televue's lenses are typically designed in U.S. and made to U.S. specs in Japan.  A few TV eyepieces are made in Taiwan (which is not a bad place to do optics) but the telescope objectives aren't--not yet anyhow.

 

So Roland will get a bunch of glass blanks from Japan and grind them on his premises.  Al Nagler will get a bunch of lenses from Japan that he designed, check them out, and assemble them into telescopes in NY.  Such is my understanding.

I thought the question was "how well traveled are your scopes"?   I've got an AP refractor that lived in England for a while and then returned to the US, it's been abroad more than I have!  lol.gif

60mm Prinz Astral (Japan)

 

102mm F10 Cosmotron refractor (British)

 

102mm F13 Vixen (Japan)

 

SW/Helios 120 F8.3 (China)

 

SW/Helios 150 F8 (China)

 

Takahashi FS128 F8.1 (Japan)

 

Takahashi FS152 F8 (Japan)

 

Televue NP101 is  (USA)

 

Televue Ranger (USA)

 

SW 120ED DS Pro F7.5 (China)

 

SW 120ED Equinox F7.5 (China)

 

SW 100ED DS Pro F9 (China)

My ES AR127 is made by Jinghua Optics in China.  Also, my Orion 180mm MCT is made by Synta in China.

The lenses are sourced from, I think, Japan, the OTA's are machined in the U.S.  TeleVue assembles the OTA's at the NY location.

Sigh; I had a 50-50 chance of getting the optical country of origin right. Thanks for the correction.

OK, my history: Tasco 6TE (Japan, serviceable, but wouldn't tolerate it today)

Unitron 70mm spotter (Japan, poor for astronomy)

Bushnell 60x700 alt-az (Japan, decent as a spotter using piggy-backed diagonals)

Pentax 80mm alt-az (Japan, first rate, especially mechanically)

SP-C102 (Japan, fair to poor optics, decent mount)

 

I don't have any of the above any more. My current stock are Chinese, and made by Synta. Optics on three scopes have been first rate; mechanics, not at as high a level. I replaced a tube clamp and focuser on a C80ED. I use a better diagonal (Tak prism) for critical viewing with the 120ED. I replaced the diagonal and got the SCT version of the focuser used as an upgrade in the C80ED. All of the replacement stuff: Taiwanese.

Therefore, I conclude there is few countries where refractor optics manufactured: (in order of quality decrease)

U.S.A., Japan, Taiwan, Russia, China.

 

And, probably, only three countries manufactures glass:

Japan, Russia, China.

Japan 2nd? belushi.gif

 

Is Schott not German? 

 

If you count spotting scopes; Zeiss & Leitz. Swarovski is Austrian.

Swarovski used to buy their lenses from Zeiss Jena. Not sure if they make their own lenses.

My count is 3 US (Tele Vue), 3 Japanese (2× Takahashi, 1x Vixen), 4 Chinese (all Sky Watcher).

The Post title as written doesn't seem to make sense given your own response post to start with.., 

 

Can I suggest rewording the topic title?

 

Best..,
