About this image

Images aligned, stacked and treated with Affinity Photo. A number of elliptical galaxies are visible, a similar distance to us as M100, plus some much more distant spiral galaxies, for example PGC3090632, mag. 17 at 970 million light years (top right of image). I was quite pleased with the detail and colours I managed to obtain with this hybrid EAA approach.
