This is a heavily cropped image of a 4 part mosaic of the Heart and Soul down into what you see here. I decided to crop it because, well, quite honestly the hydrogen is so strong in this region it takes your attention away from the cluster itself and is quite distracting.

As always, thank you for stopping on by. All criticisms are welcome.
