It looks like a high quality lens, but I want to put cylindrical pairs in front of a nubm44 and a nubm07e, I am about to start on the 07e and just use the 3x that's been used for the mitsu 638.
Anyway I have boxes of lenses and many irons in the fire, I just ordered ZVS and a spark coil, I may be building a 10um leaf toaster, but I will limit the current and have a start and run circuit.
My knife edging project is going on the back burner for now and I may pay more but I will get the exact telescope or build one, I'm just not sure about that AR coating.
Sorry for the long winded retort, if you want it grab it. It is a nice looking piece, easy to dissemble too I bet. It could have a nitrogen fill so conceder that if you dissemble.
