Masuyama 2" Wide Angle Eyepiece 20 mm - 85° Field of View - Made in Japan Reviews
1/1 Reviews
Wrote by Marcelo G. on 27.12.2025
"In my Celestron 9.25 Edge HD... excellent, just like in the Maksutov 180, very high contrast with no noticeable aberrations, but I haven't tested it on the Moon yet. I haven't tried it on Newtonians... Rain."
