Gazing into the Eagle: Exploring the Constellation Aquila
Tonight, we turn our attention to a familiar and striking figure in the night sky: the constellation Aquila, the Eagle. Known for its distinctive V-shape, Aquila is a rewarding sight for both the naked eye and the astrophotographer.
At the heart of Aquila lies Altair, the constellation's brightest star. Shining at magnitude 0.77, Altair is not only a beacon within Aquila but also a key player in the famous Summer Triangle, alongside Vega in Lyra and Deneb in Cygnus. Its proximity, a mere 17 light-years away, makes it one of the closest bright stars to our solar system. Altair's brilliance also earns it the title of the second brightest star in the summer sky.
Flanking Altair are two other significant stars that contribute to Aquila's recognizable form. To the lower left, we find Alshain, located approximately 45 light-years away. Further out, towards the upper right, is Tarazed, a much more distant star at around 460 light-years from Earth.
The Astrophotography Behind the Image
This captivating image of Aquila was brought to life through the dedication of an astrophotographer using a ZWO 2600MC camera and a ROKINON 135MM lens, mounted on an AM5 mount. The capture involved 100 images, each exposed for 3 minutes, for a total integration time of 5 hours. The post-processing was carried out using PixInsight, a powerful tool for astronomical image processing, and the data was acquired under Bortle 6 skies, showcasing the ability to pull out stunning detail even from moderately light-polluted environments.
Observing Aquila allows us to connect with the vastness of space and appreciate the intricate tapestry of stars that adorn our night sky. The journey of light from these distant celestial bodies, reaching us after years or even centuries, is a humbling reminder of our place in the cosmos.
