These colliding galaxies are called the "siamese twins".
In early april supernova SN 2020fqv exploded in NGC 4568. But when I started my data acquisition it was already too faint to be visible in this image.
I tried a mosaic which includes M58, imaged some weeks earlier.
Minor planet (740) Cantabia left trails near M58 during the night from May 18. to 19. and again during the night from May 21. to 22.
