>Excellent eyepiece series. Very high contrast and throughput with nice sharp images. Construction quality top-notch and the long er will spoil you forever. The 10mm is especially nice in our 16 inch f/4.6.

>I would like to give the Pentax a high rating, but in my 6" Apos there was considerable curvature of field. Had I not looked at the moon my rating might have been higher, but when I focused at the center of the field of view the edges were out of focus, and when I focused at the edge the center was not sharp. A very frustrating experience for such an expensive eyepiece. I had seen Saturn through the 82" at McDonald observatory through a friend's previous generation Pentax - it was spectacular - and I was expecting an even better eyepiece in the new generation. Using it for terrestial viewing during the day I never noticed this effect. ----------------------------------------------------------- I also tested this EP out on my 12" f/5 reflector and the field curvature was very prominent 80% of the way out. Still, the contrast is amazing and I saw a wealth of detail on Mars this morning when it was 17" large. Galaxies also have better contrast if you dont mind field curvature when looking in this particular EP. I would rate it a 10/10 for contrast and 7/10 for flatness from edge to edge.
