While delving around the SMC I couldn’t resist doing a shot of 47 Tucanae which I haven’t imaged for several years. This is 45 minutes exposure for each of L,R,G and B with the RGB added into L for synthetic luminance.

47 Tucanae is the second brightest globular cluster in the sky but has a much stronger central condensation than Omega Centauri. It is adjacent to the Small Magellanic Cloud and a very easy naked eye object.
In the Southern Hemisphere, we have some of the best globular clusters, including the biggest of all Omega Centauri with some five million solar masses, and this beauty: 47 Tucanae with about one million solar masses. Here’s a good shot of “47 Tuc” by Mark Nickols:
I’m still struggling with guiding issues, but just to prove my issue is not optics, I again pointed the scope southward where things don’t move around so much and snapped 47 Tucanae last night, just to prove I can manage to take round stars (as opposed to eggs, tadpoles, dumbbells, etc). I personally prefer Omega Centauri, but it’s pretty impressive nonetheless (the globular cluster, not necessarily the image).
