X-cel lx 7mm - Celestron X-Cel LX Series 1.25in Eyepieces, 2.3mm - 25mm

The eyepiece (or at least the one I got) has visible "crud" between the lenses and found its way to the back of my box very soon... never use it, except maybe for a paperweight. I have always wanted a 7mm and this is a very poor example... at 80 bucks I didn't expect a Nagler, but the out of the box dirty condition was a disappointment... I wasn't able to use or inspect it until after the return policy expired... My advice ?? Do not waste your money...save up the pennies for quality.... I have been an Optics Planet customer for years and do not blame them for this.... I blame shoddy quality and outsourcing to another country than Japan... Celestron blew it with this line.... QA/QC sorely lacking.
