I like the Edmund 8mm RKE better.  It has 8.2mm eye relief compared to 6mm eye relief with the TV Plossl 8mm.  Heck, the 8mm RKE has more eye relief than an 11mm TV Plossl with only 8mm eye relief.

I might add that Daniel Mounsey and his review of planetary eyepieces on this website, http://www.cloudynig...ryeyepieces.pdf is what interested me in the Edmund RKE and wanting to compare it myself to the TV Plossl and Delos.  It took me all of six months to find vintage Edmund RKE eyepieces in 8mm, 12mm and 15mm.

They will all be very similar except the Delos will offer more FOV and better eye relief. That will be the biggest difference!Mike

Pardon my ignorance... but exactly what is the "RKE mystique" all about ?

I personally find it very difficult to glean out differences from EPs when doing lunar observing.  So in the end, most perform quite well...So for me, the Moon is a very forgiving target that allows most all EPs to perform...

Even a very bad telescope seems to perform on the moon nvm the eyepiece.  You can also push to 100x per inch and think your scope is the cat's meow.  But you can test intrinsic resolution.  It is instructive to look at a crater in a 14 inch and a 4 inch.  At first glance they look identical but if you carefully pick out small features in the large scope youll see they're not there in the smaller one.

The RKE is a modified Kellner and it performs rather well.

People generally feel Plossls and Orthos are better, but I also really enjoy using the RKEs.

And of course the 28mm RKE has gigantic eye relief in a small body and when observing through it the eyepiece appears to disappear.

I was showing someone brand new to astronomy objects all night using some nicer eyepieces. At the end of the night I decided to show him the 28mm RKE. He was like, "woah...that's really cool!". He liked the RKE more than the more expensive eyepieces.

I will say this. They are very good eyepieces which are better than Kellners and could be debated when compared to Orthos and Plossls. Certainly nothing wrong with them. And not too many other eyepieces provide the illusion that the 28mm RKE does. I also find they do a good job for solar observing. One could probably get a full set of them for under $160 or less. Brand new it's probably better to go with a set of Plossls or Orthos other than the 28mm.
