A new image has been uploaded

Hi all,

 

A new image has been uploaded. This time, the globular cluster Messier 4 has been the chosen one. This HDR image of this rather small globular, was taken with 10 minute and 2 minute exposures. Please also note the high number of Blue Stragglers (more info in the web site), which for such a small cluster is not very usual.

You can find the image and additional info at:

Enjoy!

Josep
