Could also be the eggs of a buck moth (Hemileucha sp.), or maybe another type of moth, as the ring pattern seems relatively common....

The varnish-like covering (more intact in Sam's image, but clearly present on yours too) seems to be unique to the tent caterpillars (Lasiocampidae). I'm not sure which species would lay eggs on green ash though. (Here is an image of buck moth eggs for comparison. They appear to be somewhat cylindrical.)
