Headset bearing put in at an angle, now stuck?

Just took delivery of a second hand Nukeproof Reactor Carbon today. Absent-mindedly put the bearing in the top cup to see if it fit (no grease, not sure if this was the correct orientation) and now it won't come out despite going in very easily. It also seems to be sitting at a jaunty angle.

How should I proceed? Try to tap it out? Grease it as best I can and then tap it in? Is there a way to verify if it's the correct way around?

I think it's a Nukeproof Horizon headset, although I'm not sure.

Thanks
