I'm selling a Celestron 4-position eyepiece turret for $110 shipped in the US by Priority Mail, payable by PayPal only, please.
The turret holds up four 1.25" eyepieces, has a built-in diagonal, and is coupled to your scope with SCT threads, although it can easily be used with a refractor if you add an SCT-2" barrel adapter (not included). The eyepiece turret lets you quickly choose one of up to four eyepieces to view through, allowing you to use just the right magnification without wasting a lot of time popping eyepieces in and out.
I sold my LX200 and my refractors and now just have a big DS-16 newtonian, and the turret isn't really convenient to use with it, although it can be done.
Thanks for looking!
