Markarians Chain - Deep sky challenge

Markarians chain of galaxies in the Virgo Cluster on the border of the constellations of Coma Berenices and Virgo.

The brightest galaxy in this image is M86 at magnitude 8.9 and the faintest that I have measured is 18.8 although there are fainter but I've no useful way of measuring their brightness to any accuracy.

Image taken when within 98% of full moon giving a sky background adu of approx 45000-46000 and a nightmare gradient.

Sum of 20 x 5 minutes binned 1x1
