Remarks: |
NGC 2362 is the central compact star cluster in the
middle of this image. The object is located in the constellation Canis Major
and can be easily observed with binoculars. All the stars in the cluster
have approximately the same brightness and spectral class. There are about
40 stars of spectral type B. In the center of the cluster is the O star tau
CMa, which is a multiple system with probably more than eight stars!
(Source: Binnewies/Koenig Bildatlas der Sternhaufen & Nebel). The open star
cluster is therefore also known as the tau Canis Major cluster. At the bottom right of the image is NGC 2354, which is clearly different in appearance from NGC 2362. Other star clusters are Ruprecht 18 at the bottom left of the image and Trumpler 6 and Ruprecht 23 at the top left. The whole scene is embedded in hydrogen gas and interstellar dust. In the middle of these gas clouds are various small reflection nebulae. The most conspicuous of these reflection nebulae can be found somewhat cut off at the upper edge of the image field. It is DG118 (Dorscher&Gurtler). BlurXTerminator was used for the image (option "correct only") |

Bemerkungen: |
NGC 2362 ist der zentrale
kompakte Sternhaufen in der Mitte dieser Aufnahme. Das Objekt befindet sich
im Sternbild Canis Major und kann leicht mit einem Fernglas beobachtet
werden. Alle Sterne des Haufens haben in etwa die gleiche Helligkeit und
Spektralklasse. Es sind ca. 40 Sterne vom Spektraltyp B. Im Zentrum des
Haufens befindet sich der O Stern tau CMa, bei dem es sich um ein
Mehrfachsystem handelt, mit vermutlich mehr als acht Sternen! (Quelle:
Binnewies/Koenig Bildatlas der Sternhaufen & Nebel). Der Offene Sternhaufen
wird daher auch als tau Canis Major Haufen bezeichnet. |
