I would jump if it was local. Bet there has never been a OC in FL.

Q

 

That one's been for sale for awhile.  It's interesting, but since it is for spectrographic usage, it doesn't necessarily need to be optically excellent.   These are used for air quality monitoring and analysis...or for analyzing the rocket plume of an ICBM launch from hundreds of miles away...so it should be a decent mirror to capture something like that small.... but the price is still too high to roll the dice and find out.   Cool piece of gear.

Radio active eyepiece.

It is NOT slightly radio active as stated in the ad. It can rip a Geiger counter a good one. These eyepieces can put out.  I have a tested one.

 

Mine is in the original army box, with the original inside lining bag. The army saw fit to have that inner bag lined with metal protection. Mine slammed a Geiger counter needle so hard to the pin that there was some initial concern about having damaged the counter. I keep it in the remains of the inner metal liner, and I put foil around the whole box on the mantle. Unlike the posted one, mine is fully functional except I don't UV the amber glass to clear it up. The glass patina goes well with the brass body.

Aluminum foil?  I thought only lead was used to block radiation.

Depends on the radiation.

Are you trying to say the left coast is more weird than the right coast? Really? Big fat LOL.

Aluminum foil is near worthless as gamma ray stopper.

Thorium dioxide in the glass?

 

I've already got the beginnings of cataracts, that eyepiece is just what I don't need.

Still cheaper than driving your car through the Pacific. About  $150 TO ship

Awesome scope.   Shipping costs are reasonable.  These do not come up for sale very often.

Koji is awesome.    I would but anything from him without any worries.

Definitely worth it    even with the shipping  which looks reasonable and from such a reputable seller

 

I cannot tell you how sweet my Vixen 80fl is   optically wonderful     does great under varied power  and is a fun easy wider sweeper at low powers   especially good looking in the classic vixen white tube with vixen green gray trim......I would not part with mine   well maybe just maybe if an older FC-76 came along....

Sorry to go off-topic, but I feel the need to respond to the assertion that I have mislead the characterization of the hazards of this eyepiece in my advertisement.

 

I read your account of the testing of your eyepiece here:  https://www.cloudyni...tive/?p=8730255.  The test in my opinion was not conducted in a scientific manner.  The fact that a couple of guys playing with a Geiger counter, got the needle to bounce, is not definitive proof that the eyepiece is extremely hazardous.

 

My assessment was based on measurements and conclusions of a scientist from the Lawrence Livermore Laboratory, who published his findings in the October 1985 issue of Sky and Telescope magazine.  He measured the combined alpha, beta and gamma radiation to be 2 milliroentgens/hour.

 

"Although this is a small amount, if I were to use my lens for five hours a night on 120 nights a year, I would receive roughly 1200 milliroentgens, which is about 24 percent of the Nuclear Regulatory Commission's recommend yearly whole-body dose"

 

He went on to concede that the eyepiece concentrates the exposure on the eye, which is a more sensitive organ and thus "could have serious consequences over the years."
He concluded that since his vision is a precious asset, he would shelve the lens permanently.

 

I believe that these lenses should be respected and not feared and I stand by my description of being slightly radioactive.
