Details:
Here, at a glance, are the colours of all the stars up to the sixth magnitude in the constellations of Cygnus and Lacerta.
A total of 178 images, which, when viewed as a whole, reveal that this area of the sky is studded with stars of different hues, like an explosion of confetti.
Albireo and 61 Cygni – two of the most famous coloured double stars in the night sky – are easily recognisable, as are 30 and 31 Cygni and Omega1 and Omega2 Cygni, which, although less well known, appear intensely coloured when viewed through a telescope.
The small red ones, on the other hand, are some of the reddest carbon stars in the night sky, particularly numerous here: U, V, AX, RS, RW and RV Cygni. It is no coincidence that over a century ago, the red star hunter John Birmingham dubbed this area of the night sky ‘The Red Region’.
The image is a collage of 178 shots deliberately taken out of focus to better highlight the stars’ colours. They were then combined to provide an overview of the colours of all the stars that make up the constellations. I took them using an 18-inch Sky-Watcher Dobsonian telescope and an A5 smartphone at ISO 800.
