Default ASTRO: NGC1073 with 3 quasars

I found there are three quasars in the image I posted earlier. Per
Simbad their V magnitudes are 19.0, 19.6 and 18.9 left to right. But
the rightmost one, B0240+011, seems way too bright compared to the
others. B magnitudes were about the same as V so no strong color to
these guys. I've tracked down other shots showing them and in all the
one identified as 18.9 is too bright for that. I thought maybe it was
misidentified at the NOAO site
http://www.noao.edu/outreach/aop/observers/n1073qso.jpg
and it was the one down and to the right of it. That looked about
right. The Sky says the object is mag 17.7 on my FIT not 18.9. The
star low and to the right of it reads 19.0, just about right. But the
position given by SIMBAD is that of the bright object. So I'm confused.

See original post for photo details.

We'll just have to take a spectra and see which one is "real".........

If we went real deep with a color exposure there is a chance that the "real"
quasar would show up because it would be very blue.

Have you checked NED?
