Thanks to all who have provided a critical review of the transperancy table.
I will freely admit that the table as it stands has not been tested in the field,
It was constructed as an academic exercise taking Nth Hemisphere information and converting it to something an observer in the south could use.
On closer inspection I feel that using 47 tuc and omega cen may be a little to generous. How ever I have not been able to find adequate substitutes in my short lunch break.
Suggestions for a southern sky object that is easy to identify even for newbies that sits between mag 6 - 5
in the mean time I will hunt around myself and see what i can find.
regards
Brendan
