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. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

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? George N |
