I am in agreement with Brent on using simple eyepieces for planetary observation. I prefer orthos and my old Konigs, and even Kellners and Plossls can work very well. It's not simply a matter of wide-field not being needed, though that is certainly true for planets. Fewer elements also mean less loss from multiple surface reflections as well as increased throughput due to decreased absorbtion. Multi-layer surface coatings do nothing to mitigate absorbtion. Some wide-angle EPs also are more prone to ghost images than simpler designs. Lastly, it is a rare wide-angle EP, from my experience, that is as sharp at the center of the field as a simple design. In his book Star Testing of Astronomical Telescopes, Dick Suiter demonstrates that the center of the field of the Nagler design is a bit soft. I'm sure there are better wide-angle EPs today but the concept of "more glass" rarely does much for center field sharpness. Simpler eyepiece designs also work very well when used with a Barlow. I do own a couple of 80+ degree eyepieces and several 70 degree, but they are at least 30 years old and used for dim, extended DSOs only. For planets, I always reach for my orthos, old UO Konigs, and the occasional Plossl and Kellner. If you own a long refractor, f/12 or slower, you might be surprised how sharp even a simple Ramsden can be on the planets. I keep a couple of old Ramsdens handy for my refractors. I will also echo Brent's comment on colored filters for planetary use. They almost never let you see more detail over-all. What they do is surpress some features to allow very specific ones to be seen a bit more easily. But overall, the resolution is lessened a tad. They do have their uses, on occassion, but I highly doubt you'll ever experience a "wow" moment using a colored filter. I've only ever found them useful a handful of times on Mars and Jupiter. Sorry Debbie, but I can't give a recommendation on ES eyepieces. Almost everything in my eyepiece case dates from 1985 or earlier. I'm still an Erfle user, happy with 60-65 degree fields, for the most part. Only rarely will I break-out my UO 16mm & 32mm Widescans with 82-degree fields, or my 40mm 7/70, with the bigger scopes. They get used with my smaller, faster scopes for the most part.
