I've been selling off my hard-to-use eyepieces (orthos) to build a more comfortable line-up that will see more use. I am considering a 100 degree eyepiece in the 6 mm range, and the 6mm Ethos and 5.5mm ES are on the short list (as are the 5mm XW and the 6mm Delos). But let's focus on the widefields for now.
Can I expect pinpoint stars out to the edge in the TV101+6mm Ethos combo? What about the 5.5mm ES? I am asking because I was expecting pinpoint stars to the edge in the 9mm 100 degree Lunt/APM, but that is not the case. It's not a big deal given the price. Also, the outer edge where the stars are distorted is only used for peripheral vision, so perfect performance is not a requirement.
What kind of edge performance can I expect from an Ethos and ES?
