While my binocular observation of Epsilon Lyrae, almost two weeks ago, offered a beautiful view I wasn’t quite prepared for the stunning sight that presented itself to me last Friday night — 16.10.09 — as I began gazing through the 5 inch refractor. Although there was a tenuous haze high up in the atmosphere the seeing conditions were relatively steady and both sets of stars exhibited a single inner diffraction ring during the good moments of atmospheric stability.
Ε Lyrae 1 comprises of two stars that orbit one another every 1,200 years, shining at magnitudes 4.7 and 6.2, while Ε Lyrae 2 consists of a magnitude 5.1 and 5.5 pair with an orbital period of 585 years. Both doubles offer a dazzling spectacle even under the most light polluted of skies and are more than worthy of your time. If you’ve not taken in an observation of this outstanding quadruple star system yet then do so. You won’t be disappointed!
