Harry Siebert Optics Standard 7mm
Tonight I put my Seibert 7mm in old-but-good refreactor I recently rehabed. I'd forgotten what a piece of junk this eyepiece is. I had used the ep sporadically with a 12"dob, with fair to poor results. I had hoped for improved performance in the refractor, but the ep was really no better than a 6mm huygens that came with the scope. I've got to suspect the many gushingly favorable Siebert posts on this site.

Very strange results! and very contrary to my own experiences. No reason for suspects - your eyepiece is definitly broken. I own some Siebert eyepieces and the 7 mm also (two of them!) they perform great (believe me I own some high quality EP's e.g. Pentax, University Optics, Celestron Axiom, ...).
