Lots of crisp stars Bert.
According to UniMap NGC5155 is central, NGC5045 at the top, and NGC5120 in the overlap.
I think I need a faster laptop. UniMap detected 93655 objects, matched 1489 stars from Tycho2 immediately then took ages to download and add the 407 DSOs. I could have added the image with overlay but 200KB doesn't do it justice.
DOCdb has some observation comments.
