[quote:e3654129f0="15x70"]At a first glance, #1 look like a Plössl eyepiece. But after a while, I changed my mind.
I cannot role out the possibility that #1 is really a Plössl eyepiece, but I think that may be it is a“Dialsight” eyepiece.
I read an article which introduce different kind of eyepieces in detail. Please click here.[/quote]
