Hi Fernando, this image is close to being very good indeed, just a couple of things to fix; the whole image has a slightly mauve cast, and the sky background which is often too black, is in this case too light, so that this
beautiful globular which should be the star of the show, starts to be overwhelmed and merge into the background.

That is better, but I personally would go another small step, but obviously it is a matter of your personal preference. 5139 is King of the globulars, and should be a majestic sight, sort of in your face as the saying goes. Can I suggest that you do one another step, and one a further step, and look at all three and then choose which one you like best. The few really bright ones such as 5139, 47 Tuc, and 6752, really need a slightly darker background to make them pop.
