Astigmatism in your eyes is different from astigmatism in the optics.
I have moderate levels of astigmatism in both eyes, -1.5 in my left eye and -0.75 in my right eye. Without my glasses, any star would look like a bloated stone with quite a bit of spiking, and there'd be no such thing as a pinpoint star anywhere in the view, center or at the edge.
With my glasses on, stars look much cleaner but of course the downside is that I need quite a bit of usable eye relief, at least 14mm and 2-3mm more when I put my binoculars on a tripod. An important thing to keep in mind about usable eye relief is that oftentimes a manufacturer may claim that eye relief is 18mm only for the usable eye relief to be just 13-14mm due to the ocular lenses being well recessed and/or extra bits of rubber in the eyecups wasting eye relief. (On some of my binoculars, I've had to do some sort of eyecup "surgery" to maximize usable eye relief.)
Another way of dealing with astigmatism in your eyes is to get binoculars with a smaller exit pupil, i.e. higher mag for the same objective size. As the exit pupil is reduced, there'll come a point where it's small enough to beat back the astigmatism in your eyes. (For my eyes, that small exit pupil size is a bit over 1mm, which practically means that I must wear glasses for stargazing when using binoculars.)
Here's the site that I typically use when researching usable eye relief on binoculars of interest. (The Pinac collection is chock full of good-quality/premium binoculars, so it might be a good starting point for you to look for options on good-quality optics.)
