(Begin ZetaTalk[TM])
Because it is composed of stars, with the signature you expect and are looking
for! Your impression of magnitude is skewed, so that you look at the
stars included in that galaxy, and take that to BE the magnitude.  The 
magnitude is a sum total of all the light generated by the galaxy.  Your
perception of magnitude is thus skewed by the perception that the portion 
of an object issuing the intense pinpoint of a starlight is THE magnitude. 
It is not!

So, smooth the starlight over the galaxy, and THEN compare it to the light 
to be coming from the 12th, an area smaller than Pluto at present.
