12 or 14mm Delos?

Delos will have better Eye relief
The T2 will have better eyeplacement
The T2 much wider FOV
Also the 12T4 is nice

OK, enough of the T6 idea. Now I'm thinking of replacing my 12T2 with a Delos .. 12mm or 14mm. My 8mm Delos has a wonderful FOV. It seems closer to a Nagler than 72 degrees.
12 or 14mm Delos?
your scope is f/7?
mine is and with a 8mm ep i would prefer a 12 using a scope with a 700 mm focal length
both delos perform similarly. and compared to the T 6, they are more neutral tone which i prefer to look at star clusters

Maybe I'll just stick with the 12T2.

The 14D takes a lot of in-focus, FYI. I've not measured it, but it was a bit more than my 31 Nagler. Not a worry in SCT's and most refractors, could require some small mods in a Newtonian.
You already have the 8D so using magnification multiples, 1.6 x 8 = 12.8 which slightly favors the 12D. Depending upon your scope focal length and local seeing, the 12D may get you closer to your "average" night limit than the 14D.
Either barlows well, a possible consideration based on whatever barlow you may own.
If your primary scope is f/7, the resulting exit pupil with the 14D is 2 mm, which is about optimum for sharpness wit respect to the human eye.
I guess it depends upon what you already have in the upper-teens to low 20's as to which fits best.
Probably not a bad choice either way.

I had to get an eyepiece adaptor to drop the eyepiece down a half inch. That really is an easy fix.

If money was not a factor, I would own the 4.5mm, 6mm, 10mm, & 14mm Delos eyepieces.

I like classic glass. I'd get the Nag 20T2 as well but it's so big and heavy!
I had the 12T2 & 20T2 great eyepieces the 20t2 is a breeze to look through and I echo your comment that the 12T2 is much less fuzzy to look through than the 12T4 but when it comes to sharpness and transmission/coatings the T4 wins no contest. I would expect the new Delos or any of the newer Nags to do the same.

Update … after searching for a used 12mm Delos, I just ordered a new one. I plan to A/B it against my Nag12T2 and sell off one of them. Stay tuned.
The 12mm Type 4 Nagler was the one to own..hands down a GREAT eyepiece with excellent contrast and eye relief as it was a natural upgrade to the original Type 2.
The 12mm Delos will have a smaller field as I'm sure you know, but it also has far greater eye relief AND..a far more modern image. You'll see HUGE improvements in brightness (light throughput) contrast, field correction and lastly and most importantly to me, color neutrality. Stars appear whiter, rendering a more realistic, natural view. Planetary and star colors will be more obvious. All in all a superior view in all respects compared to the T2 Nagler or just about any eyepiece. It's a KILLER planetary eyepiece, with a good quality barlow it dominates the planetary viewing experience!
