Hello, I've noticed that some eyepiece designs use "water white glass" which is an ultra clear glass. I suspect that this may be why I found the Orion Stratus I tried to be so nice for use on colored doubles. Since then, I've done a little research and it seems that this type of glass is used by the Baader Hyperion\Orion Stratus line and by TV in the Ethos. What other eyepieces are using this type of glass?
