5 of 5 Another Exceptionally Fine Eyepiece from E. S. May 14, 2020
Reviewer: Stephen R. Waldee from Ivins, UT United States  
I purchased this ultra wide-field (82 d) Explore Scientific 1.25" ocular to replace a cheap Chinese one of the same focal length, which has numerous shortcomings and weaknesses (aside from its absurdly low price, about a tenth as much as a top-brand make by "Uncle Al".) The ES 11 mm surpasses it in every way: wider field; far, far less astigmatism; sharper resolution; infinitely flatter field with almost NO loss of focus near the field stop, even in my f/5 refractor.) It also shows fainter stars & nebulae: a total winner--performance I EXPECTED, based on my other new ES eyepieces, happily purchased from Don at EyepiecesEtc.!
