That's an amazing, fantastic picture, and I can just imagine the time it took to shoot this much sky and stitch the mosaic together! (No, I can't.)
But it is very hard to find your way through this image, because there is such a profusion of stars and galaxies here, and the stars don't have any diffraction spikes, and nothing is annotated, and the picture is "upside down". That is, south it up, and I think east is to the right.
Anyway, these are a few things I have found here:

At top left in today's APOD, you can find the bluest-looking galaxy in the field, M99, located to the right of a bright blue star, 6 Coma Berenecis (6 Com). (To the left of 6 Com is another galaxy,
M98.)
At bottom right, you can find uneven globular clusters M53 and NGC 5053. In Rogelio Bernal Andreo's picture M53 (the bright one) is located to the lower left of NGC 5053 (the faint one).
Let's get back to the top left corner of the picture. To the lower right of M99 you can find the interesting galaxy pair
NGC 4298/4302. And farther below M99 is
M100 with blue spiral arms and a yellow halo.

At top center in today's APOD by Rogelio Bernal Andreo is Markarian's Chain. At left is another picture of Markarian's Chain. In the picture at left, giant elliptical galaxy M87 is at top left, and two other giant elliptical galaxies, M86 and M84, are at bottom. Don't miss The Eyes, NGC 4435 and NGC 4438! Again however, the picture at left doesn't show Markarian's Chain with north at top.
This is how it looks with north at top in a photo by Alson Wong.

Finally, don't mss the amazing Black-Eye Galaxy, M64, at bottom left of today's APOD. In the APOD it really looks as if the galaxy is wearing a black eye patch over its core!
It's a great APOD! Does anyone feel like annotating it?
EDIT: Oh, it's been done already!
Is that you, Geck? Thanks!
