Astrophotography almost never utilises single exposures. Almost all images are the result of stacking anything from a few to several hundred frames. The larger the scope, the shorter the exposures can be, and the better the resolution will be. The difference in resolution between an 8" and a 10" would not be noticeable unless the image was to be greatly enlarged, which most are not.
