Did a head to head comparison with an ES 6.7 82* and the Pentax was not just better but a long way ahead. Looking at the Trapezium in the Orion Nebula on a below average night and could see the e and f stars with the Pentax. The ES showed the e but the f was missing. I used to think the ES was a nice eyepiece, it is...the Pentax is better.
