Mt. Ash Tree

Out in my field along a fenceline I saw this tree today. It's very beautiful, and no matter what it is I'll probably leave it alone, but I was wondering what it is. A friend of mine thinks it's Mt. Ash/Rowan. Is it? If it is, does it have any medicinal or other uses?

I used to make rowanberry jelly, many moons ago.

I also had a set of runes cut from a section of a branch and engraved with a hot iron as rowan was considered a sacred tree in wales.

I think so.  Here's a good write up about it I read recently:

I did some research, and it looks to me like a Rabina Mt. Ash. I'm going to take a closer look tomorrow
