  In this paper we discuss the prospects to take a picture of an extended
neutrino source, i.e., resolving its angular neutrino luminosity distribution.
This is challenging since neutrino directions cannot be directly measured but
only estimated from the directions of charged particles they interact with in
the detector material. This leads to an intrinsic blurring effect. We first
discuss the problem in general terms and then apply our insights to solar
neutrinos scattering elastically with electrons. Despite the aforementioned
blurring we show how with high statistics and precision the original neutrino
distributions could be reconstructed.
