Where, Jason?

All I can see are Plossls listed, and these are made to look like the old RKE. Even the ad for the Astroscan lists Plossl eyepieces, not RKE.

RKE's are a three element design, Plossls are a 7 element.

Wavy, I had thought that I was clear in asking for astigmatism correction in my first post. Sorry if I wasn't that clear. I can only guess for my lack of knowledge on optics, that fast reflectors aggravate astigmatism in an eyepiece. This is what I've noticed between the RKE, TMB/Titan II, SuperView and Q70 in decending order of image quality.

Leaving coma asside, which is the common problem to all fast reflectors, astigmatism in fast reflectors is what I'm looking to reduce in the eyepiece.
