I'd like to know the answer to that question, too. I've never seen a new Jaegers lens, and would love to hear if anyone has one or looked through one.

I have 3 6" Jaegers lenses. An f/5 that a late friend of mine built into a nice OTA; an f/10 that I built an OTA for about 10 years ago; and an f/15 that I have yet to complete an OTA for.

All three of these were alleged to be early 60's vintage. The f/10 has some discoloration on the coatings, but is a great visual planetary and visual/imaging DSO performer (it does great with planetary imaging if I shoot monochrome). The f/15 has a small chip at one edge. It's in a non-factory cell, and I suspect someone tightened the retaining ring too much. The chip is colored out with a black felt marker. I was told it's never been in a scope. It's very clean, too.
