Being impatient I take short exposure sequences. I thought at first the stacked image showed nothing, but at the center is a small ring feature. Most peculiar, as the HST images (in-set) shows:  these are interacting galaxies.

My deep sky technique is to take photos of objects at random, and then investigate further. This was a nice reward !
