Vintage Celestron Ultima 23mm WA eyepiece ZWO users wanting to use thisFeatures Japanese made, this is a used, fully multi coated 23mm eyepiece with 1. 25 inch barrel. This is in excellent but used condition: the glass is clean, as is the barrel, which shows some wear. This one was used by the Denver Museum of Nature and Science in their Questars, and has been modified for use in the shorter Questar focuser. The only difference we can see between this and a non modified unit is that the 1. 25" barrel has been shortened.
