Edmund Scientific RKE 21mm

I've owned the complete set of RKEs for over a decade. They are well made and threaded for filters. They are sharp edge to edge, no noticable distortion and bright. These are not kelner type eyepieces, I have two kelners and the RKEs are far superior. They are nearly identical to the plossels I have, a bit brighter and a little more eye relief, but a slighty narrower field of view. All said, I think these are the cheapest good quality eyepieces available and a good value.

Edmund Scientific RKE 21mm

I love Al Nagler's wide-fields, but for lunar and planetary work at high power I found a nice surprise in the Edmund's Reversed KEllner (RKE). Even when you barlow them in PowerMates 2.5x (or 5x) they show me greater detail. I use them in my Portaball 12.5" (with legendary Zambutto mirror) and my Tak SKY90.
I wish they were supplied with rubber eye cups, I prefer my eye to touch the soft rubber rather than the metal. But I will try to buy them somewhere.
