With my 70mm F/6.8 TeleVue Ranger, I keep a trio of "old" Naglers (all of which are super compact, lightweight, parfocal, immersive, comfortable (yes, even the 4.8mm NT1 smoothie!), super contrasty, and tack sharp to the very edge of the 82 AFOV)!
4.8mm original (Type 1) "smoothie": 100x / 0.79 degree TFOV / 0.71mm exit pupil
7mm Type 1 (later edition with the rubber barrel grip and eye cup): 68.6x / 1.1 degree TFOV / 1.0mm exit pupil
and the (now discontinued) 11mm Type 6: 43.6x / 1.8 degree TFOV / 1.6mm exit pupil
*For my "finder" eyepiece with the Ranger, I use a 24mm Panoptic: 20x / 3.2 degree TFOV 3.5mm exit pupil
These comprise full extent of my eyepiece "collection" and are ALL I could ever want and/or need!
PEACE,
