This may have been answered before. When I right click on a galaxy, NGC/IC, the stated magnitude is usually somewhat brighter then when I click on 'more info'. More info will bring up the NGC-IC Project data showing the magnitude to be dimmer in most cases.
Where does the 'right click' magnitude info come from? And why is there such a large difference compared to the NGC/IC magnitude info?
