For those not yet introduced to this part of the sky. M97, the Owl Nebula, is a planetary nebula with a small (visible in this image) 16th mag central star that has gone supernova. It has pushed out two lobes of space amongst the shell of gas that make the nebula appear like owl eyes.
In the lower right is a nearly edge-on galaxy, Sc type galaxy and about 45 million light years distant.
