I use my right eye but find at times that I have a little astigmatizim which at first thought was a bad eyepiece.
Tried my left and what do you know , no distorted stars .
I do wear glasses for long distance viewing but don't need them for close up , but I did not relise that there is a small amout of astigmatizim correction . Have been using the left more now but find you have to start the night out using the left or things just don't seem the same if you swap over .
