James,

A few examples...

N291 right click shows 13.9m vs 'more info' NGC-!C shows 14.5m
IC 5039 12.5m vs 13.3m
N7222 14.0m vs 14.8m

It looks like the difference may be visual mag vs B mag. But my question remains. What is the souce of the magnitude info that is shown when you 'right click' on a DSO?

tks Ben

Hi Ben
Mine seem to agree. What NGC objects are you looking at?
Thanks
James
