No, sorry, let me try to better explain... by Eta I was meaning the star its self. I notice in this (perfectly exposed) shot that this thread is regarding Eta (the star) looks non-circular, like the lobes are there, but "burnt out" by the longer exposures to get the nebulosity of the Keyhole. What I'd be interested in seeing is a shot that shows the actual lobes on the Eta star, like (but obviously not hubble quality): http://hubblesite.org/newscenter/arc...leases/1996/23

Hopefully that better explains.

Edit: I might not be correct that it's Eta the star visible in your shot here but I think it is... but that's largely irrelevant anyhow, just made me think of the idea again.

Roger.
