For starters, you can get by with your 9mm (unless you need to wear eyeglasses) and 30mm. The eyepieces rival Televue but they were sold to fund an Ethos.I missed the 16mm and regretted it as it's a very useful focal length.

As such, the Nagler Type 6s are showing their age, as newer models of eyepieces, including Tele Vues own Delos series, provide adjustable eyecups and much longer eye relief, important for us aging observers! For planets 30-40 deg. 15mm Stellarvue is identical to the 14mm ES 82, field curvature and all, as noted above. I find the Televue better, but both the ES and UWA are very close. this IS the best value in an ocular that I have found.., I'm super pleased with the product. It sounds like at $65 a piece it would be hard to do any better. In my scopes, I generally use the 3.5 mm Nagler with the 2X TV Barlow as my highest magnification. But the price is the highest. Well, that was true until the Stellarvue 28mm / 82. Of the lower-cost 82 models, this was a good choice overall for both optics and mechanics. I am fortunate that I do not need to wear glasses..

I find the 82 degree fields of my Explore Scientific 9mm to be less accessible, though it is a nice sharp view. Its long 20mm of eye relief, screw-up eyecup and large eye lens makes Orions Lanthanum a pleasure to use. At NEAF, I purchased the 16mm UWA from Stellarvue for $95. But it is an excellent and attractive, though large, eyepiece at a slightly lower price than a Nagler with much better eye relief. Don, I know the FS size controls the AFOV, but I thought the F/L was inherent to the optical design? The amount of head tilt needed to see the edges of the field are less than other ~100 degree eyepieces, including Ethos, ES, and APM. 100 degree eyepieces are quite amazing but they are also very large and can be quite heavy. Returned it. Nice detail of the moon and the cloud bands on Jupiter. Though if you want the best, this is it. I saw clear, sharp, spacious views of Jupiter and the Moon when I first tried this eyepiece, and it also works well on double stars. HOW did the Stellarvue EPs work out???? Even if they arent perfectly sharp to the absolute edge Im sure theyll be fine for most of the usable viewing range which should be good. I've used them at outreach events and the nice eye relief and the wide viewport really help the public get a good view, especially the little ones that often struggle to find the image. Fancy eyepieces are expensive, simpler eyepieces can be nearly as good and much more affordable. Buy all three of our high end 82 degree eyepieces and save! Pros: Very comfortable eye relief; superb optics. Very fast shipping and packaging. They slap on the "15mm" on the side and everybody assumes it is actually 15mm, when it is really 14mm. Make no mistake, these are large and heavy eyepieces, with some requiring 2-inch focusers. I've owned all the WO UWAN in the past but sold off all of them except the 4mm. The Stellarvue 82 is well made, with a compact, solid construction, good 14mm of eye relief (better than the stated 12mm) and a fold-up eyecup. I just purchased a SV80A (really excited) and they had deal going where you get the 8mm and 15mm for a little over $100 so I jumped on it.
