I briefly owned the 7mm Nagler Type 6. I was not impressed with it. Eye relief felt tight when observing anything bright, and it had significant SAEP / kidney beaning - especially noticeable on the Moon. Less noticeable on deep sky or planetary viewing, but still there.

If you're not familiar with SAEP, check out this thread for some examples and animations: https://stargazerslounge.com/topic/357841-saep-eyepiece-fov-comparison-in-a-127mm-synta-mak/

I would personally not recommend the Nagler 7T6, but my experience with it is evidently not the norm, so maybe you wouldn't see or be bothered by its SAEP. All I can say is that the SAEP was as bad for me as the broadly experienced and often derided SAEP in the 9mm and 6mm "gold/red lines". If you have the 9mm or 6mm red line and you see SAEP in those eyepieces, there's a very good chance you'll see it in the 7mm Nagler T6.

I also own the 7mm Astro-Tech XWA. It's a wonderful eyepiece. Very good sharpness across the field. Very good contrast. Optically it's basically right on par with a Tele Vue Ethos. Eye relief is tighter than an Ethos, but something about Ethos requires very exact eye placement distance to see the field stop, so in some ways it's more comfortable and easier to take in the field of the XWA than a Tele Vue Ethos despite less effective eye relief (hard to explain why).

However, I use it with a Paracorr 2. At F/5, you will readily notice coma in a 100 degree eyepiece (and frankly, also in an 82 degree eyepiece). Some people aren't bothered by it, but after using a P2 in my 12" F/5 Lightbridge with 100 degree eyepieces, using it without the Paracorr shows just how strong the coma is.

So between the two, I would say the XWA, but the very edges will be comatic so you won't be getting full utility of the whole field. The outer field would just have to act as context rather than something more useful.

My scope is half your focal but f/5 also. I got a Televue 4mm Delite for planetary because I read that they are very good with bright object like the moon/jupiter. Indeed, I am quite satisfied with it. I also have couple of ES82 like you.

For the Money the Astro-Tech/APM Eyepieces are a real bargain. Just be aware that you will really want to look into a coma corrector... I have quite a few high end eyepieces and if I'm honest I spend a LOT more time in the 10-31mm range than the < 10mm range, from the city the seeing is almost never good enough to support really high magnification... (I have a handful of scopes from an 80mm refractor up to a 16" dob and the last time I pulled out the Ethos 3.7 and 4.7 was for the conjunction of Saturn and Jupiter 5 years ago)

Have you looked though a 100° eyepiece?  Some people don't like them, or don't use them in such a way as to use the entire 100°. You have to get your eye pretty close to the eyepiece to see all the way to the field stop.  If you have to wear glasses then it's probably impossible to see the whole 100° fov, you can't get your eyeball close enough.

Also keep in mind 100° eyepieces are big and heavy, that matters to some people.  Can make your eyepiece case a concern, or balance of your scope a concern.

Without a coma corrector that outside portion of the view is really mostly for framing and the "feel" of sticking your head out a spaceship window. You don't really actually look at anything in that outer portion - it is just for your peripheral vision (which is naturally blurry anyways). 

I like my 100° views but it does take a bit more "effort" to use them compared to my 82s.

The AT/APM/SV Optimus 7mm XWA is excellent and the best in that whole line and would be a good one for planetary and higher power. I have the APM version. A coma corrector might be needed, but for some people it doesn't bother them at f/5. I did use a P2 when I had my 12" f/5. The new Houdini coma correcting eyepieces are getting some good feedback on Cloudy Nights, so that's an option as well. I don't have them but I've seen some discussion about possible reverse coma if you ever consider using a Houdini on a slower scope like an f/7 refractor.

Reviews for the SVBony SV245 16-8mm zoom eyepiece are really good. It's not as wide a FOV as you're asking about, but it's apparently a consistent 63° and parfocal across the zoom. And it's under $200.

Can’t see needing more than what you have currently really. Do you own a decent Barlow? It’s a bit foolish to pay lots of money for eyepieces you can seldom use due to seeing stability limitations

If you do not have Coma Corrector, buy a Coma correcting eyepiece. Houdini 7 mm 86°. 300€. At par with nagler T7, but without Coma......
