T Cancri - Carbon Star

T Cancri is a red giant variable that gets it's deep reddish color from carbon that is dredged up from its core that forms a fine soot layer that scatters away the blue and green light, much like a sunset does. T Cancri varies in brightness from a magnitude 7.6 down to 10.5 in the green light band over a period of around 482 days. It was around magnitude 8.6 when this image was taken.

La Superba

Other names for La Superba are Y CVn, and HD 110914. La Superba is a late stage red giant star, with a mass of three times that of our Sun, but with its outer layers extending out to a radius of 2.2 Astronomical units (1 AU is the distance of the Earth to the Sun). So if La Superba was at the same location as our Sun, it's outer layers would extend out to Mars. Like many red giants, it is also a variable star changing in brightness by around 1 magnitude over a 160 day cycle.
