This week it is one of my “single star” images, where the main subject is a bright star in the centre of the frame. This is a recently taken image, but I like it so much it is Picture of the Week, even though it is only 12 x 5-minute subs! Taken with the Canon 200mm prime lenses and ASI 2600MC Pro OSC CMOS cameras, Spica is the brightest, bluest, star in the sky – a true celestial sapphire.
