Description

M19 has been a weird one as I could not seem to find the right colour balance originally. It is also one of the weirdest as it is the most oblate in visible light. After a LOT of trials in PI and a lot of flattening iterations I came to the conclusion that high extinction along the line of sight is responsible of the particular colour of this GC. I wish I had better seeing but you can't have it all, especially at these declinations. Even from Sardinia!
