For all of the Nihon Seiko (Unitron, Polarex, Weltblick, Meridian, Mercurious) fans that are out there, here is yet another Nihon Seiko Refractor for your consideration - - this one is branded “Polaris”.

Being offered here is a very rare Nihon Seiko Polaris 50mm x 700mm, that I think probably picked up the best attributes of the Unitron 105 & 750 Models, and combined them into this Refractor with an unknown model number, to deliver what you see here.

While this is the only fully assembled Polaris branded set that I found anywhere on the Internet, I was able to find a thread on CN about someone who came across a (shortened tube) Polaris Finder and was comparing it against a Unitron Finder, which confirmed to me that there are 100/102mm Polaris Models out there as well. Additionally, I also know that Nihon Seiko sold Eyepieces that were branded Polaris (similar to Unitron EP’s), when I uncovered & missed out on a Polaris 4mm Ortho Eyepiece that recently sold last month on CN (Ad Number 182185).

This complete Polaris set (with the exception that it is missing the EP’s) is in very nice cosmetic condition, with minor scratches but no dents on the tube, and a small chip in the Lens Cap. While the Lens has no chips or scratches, it would probably benefit from a careful cleaning. The tripod has very minor scrapes & scratches, and the Mount is in very good to excellent condition. The Diagonal is included in the sale, but no EP’s are included. The wooden box is also in very good to excellent condition, with no splintering or breaks in the veneer.

US sale only, and if you use PayPal I will absorb the Fees, while the Buyer pays the shipping.


  • Condition Very Good!
  • Location Metro Detroit (North) area
