Digitized Sky Survey image of χ Carinae

The image below is a photograph of χ Carinae from the Digitized Sky Survey 2 (DSS2 - see the credits section) taken in the red channel. The area of sky represented in the image is 0.5x0.5 degrees (30x30 arcmins). The proper motion of χ Carinae is -0.029 arcsec per year in Right Ascension and 0.021 arcsec per year in Declination and the associated displacement for the next 10000 years is represented with the red arrow.
