I wonder if TV changed anything with the design over the years. The reason I ask is that I have an older Nagler 16 Type 5 from the early 2000's and with the eyecup folded down it's a breeze to take in the whole view without squeezing my eyeball to the ep.... ideas on that?
I seem to recall some of the Panoptics didn't have retaining rings on the field lenses, so that if you removed the bottom barrel the lenses would fall out. They had these little paper warnings about that.
I think they all have retaining rings now.
And, of course, the 22mm and 15mm Panoptics were discontinued.
And now, the lower barrels are becoming smooth, with no undercuts on the barrels.
And, the production has moved from Taiwan to Japan.
I, too, had no problem (when I observed without glasses) using the 16mm T5 Nagler with its 10mm eye relief.
It was tight, but the concave eye lens prevented me from rubbing eyelashes against the glass. The T6 Naglers seemed more comfortable, with 12mm eye relief and less concave eye lenses.
And a few nights comparing the 17mm T4 with the 16mm T5 were a revelation. I sold the 17mm but kept the 16mm.
The 16mm was sharper, had better contrast, a more uniform sky background brightness across the field, a flatter field, and no intrinsic coma.
Plus, it was parfocal with the T6 Naglers.
