Yes but 41mm Panoptic without Paracorr still has largest true field. My point is that for use as a finder eyepiece a 41mm Panoptic (with or without Paracorr) is an excellent choice. An oversized exit pupil is irrelevant (and not really an issue for people with oversized pupils). The apparent loss of effective aperture is not even noticeable as one is looking at relatively bright stars (that are also on a chart like Uranometria or Sky Atlas to hop by not 12th magnitude ones. Contrast difference is noticeable as exit pupil increases but again irrelevant for 8, 9 or 10th magnitude stars through a telescope.
I just see so often comments about exit pupils being too big as if it was a hard and fast rule. Not many people though have or want a 41mm Panoptic just for use as a finder but when you have multiple telescopes you find that you also end up with multiple eyepieces and they each behave differently in the different 'scopes.
If all one is doing is looking at bright stars to try to navigate the sky in the main eyepiece, there is no need for an expensive, well corrrected eyepiece like the 41mm Panoptic, eyepieces like the 38mm AgenaAstro 70 degree/Orion Q70. These offer the same true field of view as the 41mm Panoptic.
The exit pupil "rule" is applicable if one is actually using the eyepiece to view objects. If one is also trying to see the object of interest, then the slightly smaller field of view of the 31mm Nagler combined with the 32% greater magnification makes it better choice, at least for me. Since I am both using the eyepiece as a "finder" eyepiece to star hop with as well as a "finder eyepiece" to find the object itself, the small added field of view of the 41mm Panoptic over the 31mm Nagler is just not much help.
But we all star hop differently. I use Sky Safari so I can customize the field to use with my 50mm finder as well as the main eyepiece. I align the cross hairs of the finder vertically and horizontally and with it's 6.8 degree field of view, I have a lot of stars to work with and by precisely aligning the finder with the star field, I can put the object within a relatively narrow field, the 21mm Ethos provides 0,74 degrees at 134x, only about 21% narrower than the 41mm Panoptic. The 13mm Ethos provides a 0,45 degrees, about half that of the 46 Pan but at over 3 times the magnification.
For hunting down more difficult objects, the higher magnifications almost always are more effective because the objects are visible whereas very often, they are too small to be see in the 41mm Panoptic.
But all this is neither here nor there. I think we both agree that if one is buying one eyepiece for an F/5 Newtonian, a ~30mm UWA is a better all around choice than a ~40mm SWA... And yes, if one is not looking for the object itself, and trying to star hop on bright stars, then exit pupil is pretty much irrelevant. But then just how often is one only using an eyepiece just to star hop and not look for objects, for me, that is not very often.
For what it's worth. I bought the 41mm Panoptic specifically to increase the TFoV of the 25 inch F/5 for star hopping. With the 31mm Nagler and the Paracorr, that provided a 0.67 degree field. The 41mm Pano added field of view but it was basically a bust for star hopping. The added field of the 41mm was just not enough to make it worth while.
But in the process I did discover that my eye dilated to something closer to 8mm than to 7mm and there are occasions where I can take advantage of that.
