A Halo of Red Giant Wind around the Owl Nebula
The Owl Nebula (NGC 3587) is a double shell nebula. An additional faint halo is recently found in interference filter CCD images (Kwitter, Chu, & Downes 1992, in IAU Symp. 155). To confirm and to determine the physical nature of this halo, we have obtained spectra of the Owl Nebula with the IDS spectrograph on the INT 2.5m telescope at La Palma
