Some promising first light feedback Dave, thanks!
So far from what i'm hearing, it has very slight EOFB, slightly less sharp than the ES68 but mnore comfortable to use. I wasn't clear if you felt the unbarlowed 22mm had a sharper edge correction than the ES68 20mm in your refractor... Also, What did you mean the field stop was sharper in the OL22 vs the ES68 20? My ES68's field stop is sharp as a knife edge.
Olivon should really fix or remove that silly huge "1.25" text on their eyepieces. It's unnecessary information that clutters the look of the EP making their packaging look amateurish. Just my $.02.
I double checked my short comments to make sure I hadn't indicated otherwise, but my impression is that the Olivon seems to be just as sharp as the ES68. There seems to be some slight EOFB, but sometimes there did not seem to be any. This is one of those things that I really need more time to be certain about. I think that is the main point and why I mentioned it at all. Usually the EOFB is immediately obvious if the eyepiece has it to any distracting degree. So while I saw some evidence of low level EOFB it is very mild.
I have found that while the ES68's have a "sharp" field stop, they are not quite perfectly sharp. If you look directly at the ES68 field stop you may notice a slightly grainy edge to it - as if it just needs to be a fraction of a mm moved inward or outward. I find this with both my 28mm and 20mm ES68's. This is not something you will notice unless you look directly at the field stop. In a normal viewing it seems very sharp on the periphery, but a number of eyepieces I have are sharper. But it is not fuzzy by any means either. The Olivon has a perfectly sharp field stop.
This really is an inconsequential difference. Of more importance I felt it was easier to take in the view to the field stop with the Olivon than with the ES68. The Olivon seems to draw you in to the field stop ... "Here I am! Now relax and enjoy." (Note: personification of field stops is an early sign of needing to go fix dinner).
