Unique & rare set of Vixen Double 'Circle-V' 0.965" (24.5mm) Eyepieces with cases.
Up for Auction is a set of Double 'Circle-V' eyepieces with storage cases as shown in the photos. All eyepieces are Double 'Circle-V' eyepieces except the Vixen K-20 which is a 'Circle-V' but is included because it's unique on it's own in that it includes a removable 'smythe' lens that screws in the filter threads. (Plus, the K-20 with smythe lens fills the focal length gap, providing 10mm, 15mm and 20mm FL.) While the Celestron K-30 and K-40 are not 'named' Vixen eyepieces, they both have 'JAPAN ((V))' stamped on the barrel. The stamp is very hard to see in the pictures and difficult for me to photograph clearly.
All optics are in 'good'+ (most in 'very good' or better) condition, especially for their age. See photographs for overall condition. Note: the Plastic Vixen cases are well worn as almost all of these cases are since they're decades old. Finding these cases that are not cracked, chipped, or missing their caps is becoming increasingly difficult. The case for the 4mm ortho is very rare because it has desiccant in a separate chamber in the bottom. I've only seen one other case like this in 3 decades. These cases alone have become 'collectables' for Vixen "Circle-V" Ortho aficionados.
These EPs are great Planetary/Lunar/Star Splitter eyepieces considered by many to be the "poor man's" CZJ, back in the day. It took me a decade to build this set and I have not seen another set like it offered for sale.
This set consists of:
- Five Vixen Ortho eyepieces in original plastic cases; 4mm, 5mm, 6mm, 9mm, & 18mm.
- Then there is the Vixen K-20 with screw in smythe lens and plastic case. (Provides 20mm & 10mm FL)
- The Celestron K-30 is the newest kellner and works with the K-20 smythe lens in my Zeiss Telementor providing ~15mm.
- The Celestron K-40 is the 'elder statesman' of this set and was probably manufactured in the 50's-60's. (40mm is the longest FL you can use in a 0.965" barrel.)
Both Celestron kellners are 'Fully Coated' and come with properly sized bolt cases and original field lens caps. [a rarity in itself. ;-) ]
- Included with this eyepiece set is one (1) 1.25" to 0.965" (24.5mm) adapter.
[Winning bidders choice of adapter. Either the Delran Split-Ring adapter shown which was custom manufactured for me by Russell Optics, or a regular metal with set screw adapter (not shown)]
This set is both useable and collectable. All eyepiece have 0.965" (24.5mm) barrels. These eyepieces were 'prized' for their color rendition, clarity and transmission. They do have a 'narrow' field of view by today's standards (~45 - 50 degree FOV typical)
Wire Transfers, Money Orders, and Personal or Cashier's Check are accepted as payment. I do Not accept PayPal.
I will ship via insured USPS Priority Mail.
No 'Overseas Foreign' bidders please. If the winning bidder is outside of the USA or Canada, I will reject that bid and offer the set to the next highest North American/HI bidder.
Winning bidder pays an additional $15.00 shipping and insurance. (An additional $7.50 USD cost for shipping to Canada)
For those not familiar with the Vixen markings, there is the more common 'Circle-V' eyepiece sold under various brand names like Vixen, Celestron, Carton and several others. These optics have a "V" inside a circle stamped or marked on them which is the Vixen trademark. This indicates the optics were manufactured by Vixen regardless of the name stamped on the optical equipment. The 'Circle-V' eyepieces have been recognized for years as having outstanding optics. If you are unsure of the difference between the common "Circle-V" and the Double 'Circle-V', see the picture of the Or.6mm next to the K-20.
The origin of the less common Double 'Circle-V', is shrouded in mystery and has had people speculating for decades. Back in the day, the two most prevalent theories of the origin were: 1) They were a "premium" manufacture of the optics. 2) They were simply manufactured at a specific factory.
While many people claim they know the answer to this mystery, having grown up in the 1950's & 60's hearing and reading all the debates, my personal opinion is the Double 'Circle-V' was first stamped on Vixen optics to indicate a "better grade" optics manufactured at a specific facility. Many years ago I met a knowledgeable amateur in Japan who worked for Vixen in the 1950's & 60's. We discussed this mystery and he said, when he worked there, Vixen had several plants that all used the "Circle-V" stamp but only one plant used the Double 'Circle-V' marking.
I am sure others will argue with my opinion. Their opinions could be correct but ask yourself this, why would a manufacturer go to the added expense of producing a special stamp for just one manufacturing plant if there were not some difference?
