VYSOS BV Ri surface brightness vs. visual extinction in LDN 1780. The relationships are shown from bottom to top in different colous: B (blue dots), V (green, shifted by +20 units), R (red, shifted by +40 units), and i (magenta, shifted by +60 units). The black crosses at AV = 0.43 mag indicate the zero level for each surface brightness band.
