Hi Serge!
to the forums!
How did you hear about us?
I've seen those Andrews ED eyepieces as well, and wondered about them myself. They don't claim to be widefield or anything, so maybe they're trying to be planetary/lunar eyepieces. I'll see if I can get a couple to do a review of them.
I'll try and find out the specs.
Hope to see you back at the forum regularly!
