This 2 inch eyepiece is our widest field in the 82 degree range. Fully-multi-coated lenses, rubber grip, 43 mm field lens and 2" filter threads. At under $200 this eyepiece is a great way to get those wide views at a reasonable price.

Great wide field eyepiece
I tested the 28 mm last night for half an hour or so from my Bortle 8 sky.
I tried it on Orion's belt, M42/M43 and Collinder 69 (cluster around Lambda Orionis).
I have a 70 mm F/6 StellarVue ED, so 420 mm focal length and this particular eyepiece gave me a very wide 5.5 degrees field at 15x.
Stars were pinpoint across most of the field, only the outer 5% or so showed some coma.
Orion belt fits well in the visual field, all of its stars were pinpoint dots, Mintaka companion (mag 6.8 at 48") was clearly separated even at 15x.
I could split 3 of the Trapezium components (even at this low magnification) and M42 nebula showed some interesting structure, which was just an amorphous blob on my 15x70 binoculars (note that we're talking the same magnification and aperture).
Collinder 69 cluster was beautiful, I couldn't split Rigel (would need 60x at least) but it was pure blue-white dot, same for Betelgeuse as an orange point. None of them had any sparks or color halos around which speaks well of the optics behind the eyepiece and the scope itself. Great purchase indeed !
