point sources

I thought that agn's and qso's are point sources. But a lot of times, like in this image, visually they doesn't seem round in DSS and 2MASS-images. Is this an illusion?

You're right that most of AGN's and QSO's are point sources, but not always. If galaxy itself is bright enough, it doesn't have to be point source.
