Description
The low surface brightness Universe is one of the last frontiers in observational Astronomy, even a deep large multi-band survey such as the SDSS/Stripe82 is essentially blind to the presence of small (<10 arcsec) extended sources with surface brightness fainter than 28.6 mag/arcsec2 (Stripe82 limiting surface brightness in the r-band). At surface brightness levels fainter than 29 mag/arcsec2 the night sky looks extremely complex, with multiple features such as dust filaments, scattered light from both stars and galaxies, extremely faint objects, tidal features around galaxies, etc. In this context, removing the scattered light produced by the brightest point-like sources is essential to exploit the deepest data. In this contribution, we introduce an automatic method to characterize and remove the scattered light in all 5 bands (ugriz) of the SDSS-Stripe82 survey.
