A composite image of the four brightest globular clusters in the night sky including; Omega Centauri (NGC5139), 47 Tucanae (NGC104), Messier 22 (NGC6656) and NGC 6752 (the Pavo or Peacock cluster).

All of the original images have been posted here on Astrobin and were captured with my Tak TSA 120 @ f5.6 and QSI 683 camera from my backyard observatory in the Central West of NSW Australia. We are fortunate at our southerly latitudes to have easy access to these objects for imaging. Given their grandeur they are thoroughly deserving of being placed on display here together.
