11 o'clock. Lens or just a nebula?
by Tom_Collett scientist
The top most elliptical might be a lens- how did the 'arc' look in bluer? Does it carry on or is that my imagination?Any sign of a counter image? If there's no counter, I suspect it's a burst of star formation in the elliptical.
I'd be surprised if any of the other objects are lenses.
