There’s been rather a trend on this blog towards pairs recently and to continue this theme here’s an image of NGC 4567 & NGC 4568, sometimes known as the Siamese Twins. This pair of interacting galaxies are part of the Virgo cluster and for some years were considered a line of sight pairing as there’s no visual evidence of interaction.
This image is the result of a stack of 14 five minute frames taken on GRAS-4 over two nights.
