Hi: I just received an eyepiece I purchased from a company on eBay; a Meade 26mm, series 4000 QX, 2”eyepiece. I got a real good deal, about 1/4 of the original cost. The eyepiece looks new. I have purchased a lot of eyepieces off eBay. In fact, I enjoy the search. I am either looking for a specific eyepiece to complete an eyepiece line, or I’m just breezing through checking out what’s for sell. I have a lot of eyepieces, most of them are good, solid oculars. I have purchased top of the line plossls, such as TeleVue plossl, Meade series 4000 and 5000 Super Plossl. I have also bought several Kellners: a 4mm, 10mm and a 25mm. Also, a 20mm Huygens and once, an SR4. These were purchased to compare with Plossls and other more advanced configurations. The trick with thus group is finding those that are well made. I purchased several “wide view” eyepieces: Meade QX, Antares 72 degrees, and on. I normally purchase economically priced wide views as most of my scopes are slow, F6 and lower. Thus, they provide me with satisfying views. There are several lines of eyepiece I have tried to complete like Orion Sirius plossl and Meade series 4000. The QX EP I purchased brings me closer to completing that line. Considering my time for serious observing, I have bought some top level plossls and an Ortho. These do a very good job since my main targets are planets and brighter DSOs. I like a lot of good quality EPs rather then a few very good and very expensive EPs.
