Carbon star in Lyra
Star-hop chart
The very red appearance of T Lyrae is unmistakeable when seen through a telescope of any size. It is classified as a carbon star because there is a large amount of carbon in the star's atmosphere, which absorbs light at the blue end of the spectrum but allows the red wavelengths to pass through. It is about 230 times as luminous as our Sun.
