I remember seeing this globular one night while south of the equator in the Fiji Islands in late October 2003. I had only taken a borrowed 5 inch antique Celestron Cassegrain but it was an eye stunning sight after I thought it was just a bright 4th magnitute but naked eye fuzzy star. From the very dark skies in Fiji I was amazed that it was a globular as we only have M13 in Hercules in the northern sky as a bright globular that approaches barely naked eye yet only from dark skies. John Dobson also says 47 Tucani is his favorite globular. Many amateur astronomers have never been south of the equator. You are so lucky to live where you do! You still have many of our northern sky wonders but the addition of so many other fantastic Deep Sky Objects.
I looked at Omega Centari one night for over an hour through a new 10" Newtonian that I took on another trip. Omega Centari gets allot of attention from those who reside in the southern US but it does not have the surface brightness or compacted stars like 47 Tucani. Omega Centari is the apprarent size of the full moon and I thought I saw patterns in it that appeared as craters or circular voids, especially one very large roound void toward the center. I wished I had sketched it then because photos of it do not show this. Perhaps your sketches will include Omega Centari eventually. I remember it is in the southern sky at mid evening in the season of June ~ July, your winter but still balmy nights I experienced in Fiji then.
I look forward to seeing your future sketches,
