Does anyone have any experience with the 68* Argon purged series from Explore Scientific? Thanks.

Orion xt10 Dob, Meade 5000 series 5.5mm Plossl, 10 and 25mm Sirius Plossls, Orion 32mm Highlight Plossl, 82* Explore Scientific 14mm 82, and Zhumell 2x ED Barlow on the way.
They are really good, I like them better than the 82* which is a really good series.
I use the 28mm as my main finder EP.

I had the 34mm and liked it a lot. I sold it when I decided to get all the ES82s. I also preferred the 68 in my SCT because the field curvature of the C8 is less apparent with 68 than the 82. But, I found the 82 preferable in my Dob.

That statement is interesting because I last owned a Dob more then 10 years ago and now use Scts and Refractors and I sold off my Naglers and converted over to Panoptics for lower powers and Pentex XW's for high and medium powers...for exactly the same reason(s)field curvature and pin cushion ..
Now I have to sit down and figure out if it is my aging eyeballs or the type of scope that caused me to dispose of my 82 degree eyepieces in favor of the narrower 68-70 FOV eyepieces..

I recently purchased the 16mm 68* and it's my new favorite EP. Open clusters "pop" in a way they don't with my celestron kit plossls, and the eye relief is significantly improved. Even faint objects in my heavy LP looked like objects, not chance groupings of stars.
I just got the ES 34mm 68 and it is a very good EP.
What is the eyerelief, I have glasses?
Thanks - Alan
According to ES, it is 11.9mm, which really isn't that much. But it seems like more. *shrug* (I also wear glasses but I do take them off while observing.)
I have new Celestron Ultimas LX 2", has 14mm. Does not seem like a lot, but OK!
