Thanks for that. So I should do some more exposure on this to pick up that faint halo structure. Thanks very much for pointing that out as I often look for galaxy targets where I can pick that sort of thing up.

I have seen a few amateur CCD exposures that go as deep as Malin's "stacked UK Schmidt films" images (which is what the second image in my post is). So it ought to be possible for you to pick up more of the strange and oddly shaped halo around M86.
I think that there are also some strange low-contrast shells or ripples in the light of M86, which are obvious in some images......these might be the relics of a merger with a lower mass galaxy.
