I am nearsighted with fairly bad astigmatism that requires -4.5 correction. However, I never observe with my glasses because I can't really see a difference with and without them on. My 35 Pan is the lowest power eyepiece I own, and produces a 3.5mm exit pupil in my SCT, but I don't see any difference in the view.

What visual aberrations should I notice with that kind of astigmatism?
