 "The Summer Triangle is a very obvious asterism in the summer sky over Lowestoft at the moment. Altair-Alpha Aquilae is the Summer Triangle star closest to the southern horizon. This part of the sky is literally full of stars, sometimes referred to as 'star-clouds' and these clouds are punctuated with dark nebulae. Dark nebulae are concentrations of dust and gas, which obscure the stars within and behind them.

The stars, Altair and Tarazed, are very different and have different spectra. This difference is obvious to the naked eye and manifest in the differences in colour. We used the spectrometer manufactured by the Observatory's instrumentation engineer, Jolene McSquint-Fleming, to obtain spectral profiles for these stars". Kurt Thrust current Director of the Jodrell Plank Observatory.
