Flowers always make a good Photo. This was was set against a very dark background to highlight the light and subtle colours of the flowers themselves.
"Messier 5 (M5) is a bright globular cluster located in the northern constellation Serpens. It lies at a distance of 24,500 light years from Earth, in the galactic halo of the Milky Way."

This image is a labor of love. Originally begun in 2022 and finally finished this year. It is comprised of images from 2 different telescopes, 2 different cameras, two types of binning, and 9 different exposure lengths. I had no idea how difficult it would be to marry all this data together. Finally, here it is.
Discovered in 1702 by the German astronomer Gottfried Kirch, M5 is one of the oldest globular clusters in the Milky Way galaxy. With an apparent magnitude of 6.7 and a location 25,000 light-years away in the constellation Serpens, M5 appears as a patch of light with a pair of binoculars and is best viewed during May.
A majority of M5’s stars formed more than 12 billion years ago, but there are some unexpected newcomers on the scene, adding some vitality to this aging population.
Stars in globular clusters are believed to form in the same stellar nursery and grow old together. The most massive stars age quickly, exhausting their fuel supply in less than a million years, and end their lives in spectacular supernova explosions. This process should have left the ancient cluster M5 with only old, low-mass stars.
Yet astronomers have spotted many young, blue stars amongst the ancient stars in this cluster. Astronomers think that these laggard youngsters, called blue stragglers, were created either by collisions between stars or other stellar interactions. Such events are easy to imagine in densely populated globular clusters, in which up to a few million stars are tightly packed together. Text from NASA/Goddard

M5 V2 is perhaps slightly better. V2 used a masked stretch, which made the stars smaller but resulted in a clouded overall look. In V3 I decided to go with a more conventional stretch for better clarity.
