These are Super-Plossl eyepieces from GSO with possibly the best contrast in the middle-price range. The accurately polarised surfaces and the renewed anti-reflexion coating make their contrast even better.
These eyepieces, that otherwise come with an average transmission value of 96.4%, have a maximum transmittance above 98% in the range of orange light!
Just for clarification: these are sometimes being called "Plossl", sometimes "Super Plossl" eyepieces. Never-the-less these are the same...
