Think Tucana + globular cluster and the first thing that comes to mind is probably 47 Tuc. However, NGC 362 is another nice glob in Tucana.

This was another one of my November pics taken under less than ideal conditions. For this glob it was poor seeing and scurrying clouds with consequent "guide star faded" messages from Maxim. So I decided to let the scope go unguided for an hour or so while I went back to the Wiruna kitchen for a glass or two (or three) of red and then later picked out the best subs to process. I think it turned out OK.
