6" F8 DOUBLET ELEMENTS ONLY - NOS - $175 SHIPPED USA

Chinese made new old stock "154/f1200" (6" f7.8, but f8 once it gets mounted in the cell) achromat (I'm assuming) element set as shown. No cell.

Matched set, you can see the alignment marks on the sides and the separators. I have four of these sets, all the same configuration. Note the Chinese writing on the outside of one of the packages in the photos, Google Translate says it's saying "Just align the energy-increasing directions!", which I assume to mean what we call alignment marks. 

A significant amount of documentation came with these as shown, I'll included copies with each set. There is more to the email string but not much relevant to the subject, just shipping notes and such.

Note the reference to the measured diameters in two of the documents. I have sets numbered 2, 8 and 5, with the last one no number, the one shown. Obviously you'd have to measure the set yourself to confirm the size but this gives you a head start on the cell requirments. 

Also note the reference to 1500mm and 1800mm sets, all 6" (so f10 and f12) in the same batch, I have two of each and I'll post those in a separate AM ad after I get back from my eclipse trip. 

All four of these are in like new condition and have been well packaged and stored. Each element is wrapped separately. 

I bought a large estate lot of astro stuff, these were in it. More to come, lots more. 

$175 per set shipped to a USA address, PayPal preferred ("Goods or Services" only please) but not required, no fee to you, I'll pay it. Note if PayPal is used I can send only to the address that comes with the payment.
