Location of the metal-poor star [[HD 196944]]

Summary

DescriptionEso0129a.tif	English: The Belgian and French astronomers decided to use the Coude Echelle Spectrometer (CES) at the ESO 3.6-m telescope on La Silla, a telescope/instrument combination offering some hope of success for these difficult observations. Spectra of three southern stars, HD 187861, HD 196944 and HD 224959, were obtained during two nights in September 2000 and found to be of excellent quality.

Image title	One of the three Lead stars, HD 196944 that was analysed in a 2001 research programme (at the centre of the field). This star lies about 1600 light years away in the constellation Aquarius. At magnitude 9, it is not visible to the unaided eye, but easily seen through a small amateur telescope. The detailed spectroscopic study reported in the associated press release revealed a high abundance of Lead in this. The spikes seen in this photo are an optical effect in the telescope.
