Do you have any oddball eyepieces. Rodenstock 40mm, Leitz 30mm 88°, a Pentax XL 60mm, Celestron Ultima 2" or ex-military/specialist? Or a ball eyepiece, ultra short or long focal length, radioactive (uranium, thorium, barium) glass, or hand made antiques?

 

Anything old &/or deviating from the norm these days, any converted from other equipment. The odder the better.

I have two .965" 9mm Lit Reticle Televue EP's... one complete, one missing the illuminator...

 

Probably not so oddball, but you don't see them often a 2mm-4mm TV Nagler zoom...

I used to own the Pentax 60 XL and since I own the rest you could say I may have been the only person in NA with a Full set of Pentax XL eyepieces. However to use it you need either one of the big Pentax APOs (150mm to 250mm) or the 125 APO and the special Pentax adapter. What I had was the Borg 150ED. The Borg focuser was large enough so an adapter to 86mm could be made for it, which I did but of course only straight thru observations as no common diagonal was available to mate it too. Used it on occasion then sold it to a lady in Italy with one of the Pentax APOs. I own a couple of original Rini 2" eyepieces in the 60-75mm range. I also own a UO 55mm Plossl. I already owned the other 2 in that range from the past, the TV 55 and the Meade 56mm SP "smoothie".

That's oddly a Masuyama clone.

I have this 2" surplus military eyepiece purchased from Edmund Scientific back in the early 80's. It weighs just under 1 pound. I have no idea on its optical configuration.

I think thats the only eyepiece that I own that might fall into the unusual category. It's a great little high power tool smile.gif

Why is it odd I hear you say?

Apparently it can cause cancer, birth defects and reproductive harm, but only in the State of California.

Well, I don't think they fit your description, but I have a few oddballs that I don't store in my eyepiece case or list in my signature. And those are:

 

2 no-name ortho's, 12.5mm & 9mm. The seller said they were Kokusai Kohki, but there was no name on the boxes or the eyepieces themselves.

1 Vixen HR 2.4mm

Sheesh, you guys desperately need that 1.6mm Vixen HR to fill the gaping hole in your collections.

 

My only oddies are the 30mm plossls that used to come with the Arcturus binoviewer (circa 2014).  Optically nothing special I suppose, but because of their peculiar design they require significantly less inward focuser travel than any other oculars I have used.  They can reach focus in BV configurations where other EPs don't come close.  And they have smooth barrels!  Even the Apollo 11 can't boast that!

Is a Meade 10.5mm Ortho with a silver anodized aluminum barrel an oddball?

Probably.

How about a 6mm Vixen NPL with eyeguard removed and a William Optics barrel?

That's it! Are those the ones in your signature that you aren't sure of?

 

 

How do you like the HR?

I honestly haven't used it that much, maybe a half dozen times [and only in my Apo, 379x]. It has a similar view to that of the ortho's. For such a high magnification, the image is quite bright. My memory is a little foggy for the most part though. I'll see if I can get some use out of it my next night out and do a better assessment.

I've got this which I have used with a 2X Ultima barlow in my 100mm F7.4 Tak, and its excellent. That's got to fall in the oddball category!

 

I'd like the 1.6mm too!

Do Baader Eudiascopics and SVBony aspherics count as odd?
