In 1826 Niccolò Cacciatore discovered a globular cluster from Palermo, Sicily.
It was the only deep sky object he discovered.
He found it while looking for the magnitude 6 Comet Pons 1825IV, just above his southern horizon, shortly before dawn on 19/3/1826.
The globular cluster was only 5.5 degrees above his horizon when twilight started at 4:45 am and it was also just above a mountain.
Here is some info on Cacciatore.

James Dunlop found the same object 3.5 months later from Parramatta in Sydney.
He described it as "A very bright round highly condensed nebula, about 3' diameter. I can resolve a considerable portion round the margin, but the compression is so great near the centre; that it would require a very high power, as well as light; to separate the stars; the stars are rather dusky."
Here is some data on this Globular cluster.
Names: Cacciatore 1, Dunlop 473, John Herschel 3726, NGC 6541
Globular cluster in CrA. mag 6.3, size 13.0', distance 23,500 lyrs, RA2000 18.134, dec -43.70
It is the 12th brightest GC in the sky after omega Cen, 47 Tuc, M 22, NGC 6752, M 4, M 5, NGC 6397, M 13, M 3, NGC 2808 and M 15.
To see the GC start from lambda Sco (the tail of Sco) and sweep 4 degrees across to iota1 Sco then continue 5 degrees along that line to Cacciatore 1. Here is an image by Steven one of our IIS members:
