Or three galaxies in the constellation of Leo, aka the Leo Triplet :)

It was acquired in split sessions during the nights alongside the Rosette Nebula, where I photographed the Rosette Nebula at the beginning of the night and the Leo Triplet during the second half of the night...

So if you want, check out the timelapse from the previous post, and at 0:27 you will notice how the telescope moves to a different target, which is exactly this one.
