Toby Jug Nebula – the bipolar reflection nebula IC2220 associated with the AGB star HR3126. (a) Color-composite optical image taken with VLT/FORS1 (FOcal Reducer and low dispersion Spectrograph) in the ESO Cosmic Gems Programme. The blue shows the B-band filter (central wavelength λ_c = 429 nm) and [OIII] filter (λ_c = 500 nm), the green the V -band filter (λ_c = 554 nm), the orange the R-band filter (λ_c = 657 nm), and the red the Hα filter (λ_c = 656 nm).
