Celestron telescope refractor cassegrain eyepiece 1.25" 30mm Ultima 1988 Japan:
This sale is for a 1988 Celestron (Nihon Seiko or Vixen of Japan) 1.25-inch Ultima 30mm. In this rare offering it will come with BOTH original dust caps, the original, large rubber winged eye guard, and the original baggy for the eye guard.
Inspect the photos closely. This is in top collector's grade condition and is simply beautiful in that it has survived this long in this kind of condition. The only thing that could have made this better was having the original cream-and-orange striped box.

In many of my personal reports I have cataloged for my own, massive references on vintage telescopes, I use Ultimas as a benchmark for visual optical quality confirmation as these eyepieces are so well made and produce such bright images (especially to the edge of field), if you see fault in your images, it will not be this eyepiece, but within the telescope itself. I do not pull-out my Ultimas to any telescope on any given night. The seeing must be steady, the air dry and the telescope worthy.
Any Ultima eyepiece from Nihon Seiko and/or Vixen of Japan will give paramount sharpness and detail in your Takahashi FC-100, Orion VX-90 Fluorite, Astro-Physics Star12 ED, Celestron C11 Edge, Meade Maksutov 7, Ceravolo HD145, or Pentax 105SD to name a few of many fine examples of top grade telescopes in which this eyepiece will help fully exploit their optical greatness.
A pinpoint-to-the-edge 50-degree field of view awaits your eye. The long eye relief means you'll get the entire view in even with eyeglasses left on. Outstanding to use on the Moon, M31, M42, the Double Cluster, M57, M4, M8, M20, and many other large deep sky objects. In apochromat telescopes, the view will remain color free and there is NO introduced coma or astigmatism. It is, by all accounts, a Takahashi LE, but with less eye relief.Try this on NGC7331 in a Wilkinson, Beck, or Zambuto 10 to 16-inch mirror reflector. Break apart M13 in your Meade 14 ACF LX200, C11 Edge, or Takahashi Mewlon 300; you will LOVE the sharpness and contrast!
Though not as rare, these Ultimas are identical to Orion's long-standing Ultrascopic line, which were manufactured by the same firm in Japan, and this also goes for the rarely-mentioned Parks Gold Series and Antares red-lettered and green-boxed plossls.
If you have an ocular turret with other additional Ultima eyepieces, they will be parfocal. I have done this both in my Takahashi FS-152sv and Takahashi FCT-150.
For a fun fact, this is one of the very earliest of the Ultimas you can find; the painted characters are Chevy orange, not ruby red, and is one of the defining features of a 1980s Ultima model.
Packed with great care. Higher cost in shipping indicates this MUST be fully insured to all global locations. For those in other nations, this can only go priority international so that it may receive full insurance benefits. WILL NOT SHIP in a USPS priority small flat rate box!! This eyepiece is too large and will bulge the dimensions; that box will NOT provide the protection this eyepiece deserves.
