Superb!
I bought a pair of these eyepieces to use with my 100mm objective binoculars. I was skeptical that they would focus properly, but that was not a problem! The 32mm focal length of the eyepieces and the 525mm objective focal length provided a 16X power and a terrific apparent wide field of view due to the plossl design of the eyepieces. The only chromatic aberrations are those of the objective lenses. The eyepieces that came with the binoculars provide 20X and 40X magnification which yield a 5mm and 2.5mm exit aperture (respectively). These new plossl eyepieces give me a very comfortable 6.6mm exit aperture with sufficient eye relief to permit using my eyeglasses.
it's in my scope all the time.
I start out with this eyepiece on a lot of my scopes. for the cost it's got a good field of view and the stars are good most of it.
Better than expected
I use this for my wide field views. It is a quality eyepiece all round, and along with my 15mm 68 degree, my most-used eyepiece. I believe the AFoV is between 50 and 54 degrees, I could be wrong, but it doesn't look like a 46 degree eyepiece to me. The field stop diameter agrees. Being a Plossl, it is also quite light. A really great eyepiece I can't imagine not having.
