This eyepiece was shipped with my Celestron 80mm ST, so I'm calling it a "Celestron" (Note: Doesn't actually say Celestron anywhere on the eyepiece or on the box). This is a duplicate focal length for me, so it's for sale "New In Box".
10mm Plossl - Made in China - Multi-Coated - $17 + shipping
Price does not include shipping. That will be determined based on your location. Please include your ZIP code in your response. USPS Money Order is preferred payment method. I'll take a personal check, but it will need to clear the bank before I ship unless you have a trustworthy Green, Purple or Gold five star Astromart rating.
Thanks for looking, Ed
