The Internal Extinction Curve of NGC 6302 and its Extraordinary Spectrum
In this paper we present a new method for obtaining the optical wavelength-dependent reddening function of planetary nebulae (PN), using the nebular and stellar continuum. The data used was a spectrum of NGC 6302 obtained using the Double Beam Spectrograph on the 2.3 m telescope at Siding Springs Observatory over three nights. This resulted in a spectrum covering a wavelength range 3300-8600 Å with a large dynamical range and a mean signal to noise of >102 Å-1 in the nebular continuum. With...[Show more]
