This is the Multiple Ocular Holder offered by Celestron for years. It is marked "Made in Japan". It works quite well and is cosmetically and optically excellent. It fits the standard Schmidt-Cassegrain thread, but an adapter should attach it to various refractors. It holds four 1.25" eyepieces; not included. This is not the turret for sale, it is the same model as in the photo taken by Phillip Houston. $100 + shipping/insurance.
I can't reply to repondings until morning.
