Mark the Deep Sky Objects


Latin: Canis Major (CMa)
English: Big Dog Spanish: Perro Mayor
German: Grosser Hund French: Grand Chien
In mid of march Canis Major can be observed best in the evening at about 20 h local time, when it culminates (see lines). The position is southeast of januarys Orion at a declination of -20 degrees. So for observers in northern hemispheres Canis Major never reaches high above the horizon. The galactic plane is crossing our field of view and so there are a lot of galactic deep sky objects, especially Open Star Clusters. Striking is the brightest star in Canis Major: Sirius (Alpha Canis Majoris). With an apparent magnitude of -1.6 it is the brightest star of the entire night sky.
