Coronado CEMAX

Has anyone out there had the chance to compare the CEMAX to a good plossl, RKE or ortho for H Alpha observing? I'm tempted to get a couple of CEMAX's if there really is a noticeable improvement in HA observing, but right now I'm kinda skeptical that it may be more of a marketing gimmick than anyting else. Thanks in advance.

My school has some of these. I'll try to get info on them.

*******

By the way, since we're on the topic, I threw a Pentax 14XL into my Maxscope 60 the other day.

It surprised me because the surface features became much more contrasty than any of the other eyepieces I tested ( including Naglers, Radians, Plossls... even Monocentrics! ).

Is there something about the coatings that work especially well for H-alpha visual?

Was it my imagination? Has anyone else directly swap/compared the Pentax's and found the same result?

Cheers
