Superb eyepiece. I had a night of incredible of viewing with extremely steady atmospheric conditions. I moved to Jupiter and plugged in my new 8.5mm LER. The view was incredible. The eye relief for me was perfect since I am an eyeglass wearer. I bought a second one so I could use it in my bino viewer.
