Well
I just spent an enjoyable couple of hours this afternoon going through the CN's Eyepieces fourums , over 550 posts covering 22 odd pages , whew !.
The overwhelming number of the posts speak very highly of these eyepieces , especially the 23 and 10mm ones , the 4mm seems to be a pot luck affair with some good and some plain terrible
, so I would say what the consences's is , is that these are one of today's major bargains ,
. They seem to have originated from a cancelled Celestron order ( for whatever reason ? ) hence the orange colouring.
But be aware that the design of there ( not their build quality ) lends these to perform their best in f7 and above scopes .

ps. go over and do a search in Cloudy Nights eyepieces forum's of ' Vite Aspherics ' and have a ball reading the views of many
as I did .
