Vernonscope Brandons are 100% American made from glass melt to figuring to barrel to assembly.  These are the only consumer-grade eyepieces the US military are allowed to procure.

All Tele Vue eyepieces are US designed and are made in either Japan or Taiwan with no Chinese made content.

All Pentax eyepieces are assembled in the Philippines, most likely from Japanese glass.  Pre-Ricoh buyout ones are 100% Japanese made.

All Nikon astro eyepieces are made in Japan (I think).

All Takahashi eyepieces are made in Japan (almost certain on this).

Noblex are made in Europe (might still be Germany, they're going through a rough patch right now).

All GSO eyepieces are made in Taiwan, although it's not clear if they have Chinese made components.  They tend to be sold under various brand names as well.

Long Perng eyepieces are also made in Taiwan (I believe, and again with possible Chinese components) and sold under various brand names worldwide.

APM labels their eyepieces as Germany, but they are made in China.

Baader is a German company, but their manufacturing is in China.

A lot of vintage (pre-2000) Orion USA, University Optics, Vixen, Meade and Celestron eyepieces were made in Japan or Taiwan.  They will be marked as such on the chrome or black barrel or have a circled letter maker's mark (definitely Japanese then).  Sometimes, only the original box mentions the country of origin on lower end eyepieces.

Many premium spotting scope and microscope eyepieces (both new and vintage) that can be adapted to astro use are (were) made in Europe or Japan (Leica, Zeiss, Swarovski, Meopta, Nikon, Olympus, etc.).  Ask here or on Cloudy Nights for confirmation on specific models.

Truly vintage American Optical and Bausch & Lomb microscope eyepieces are 100% American made but will require adapters for astro usage.

I'm sure I missed a company or two in there, but this list will at least get you started.

Thank you very much. Can you help determine which sizes of eye pieces I need for viewing deep space and planets? Assuming a 2” barrel.

Hello all, first time post and a new telescope owner. It would be great if I could get some help identifying the equipment I need. I have a Skywatcher Classic 200 (8”) and nothing else other than  a 25 and 10mm Super MA eye pieces that came with it.

I live in Oklahoma USA just outside of Tulsa. The sky’s here aren’t too bad to the east but there is a lot of city light to the west.

What “non Chinese” made eye pieces would be good for viewing Andromeda, the planets and other nebulas? I try not to buy things made in china for a variety of reasons. I’d like to stick with Japanese or Taiwanese made glass. I am on a budget but I don’t mind saving up for quality glass. I’m open to used eyepieces as well as new.

I also need to buy the following:

1. Moon filter

2. Phone holder for eyepiece

3. Phone holder so I can put the phone in front of the finder scope and use a star finder app to locate what I want to see

4. 90 degree adapter for finder scope or new finder scope with 90 degree eyepiece.

Which star/planet finder app do you prefer?
