NGC 3293 The Gem Cluster-4-Telescope Live
NGC 3293, 60 minutes of integration in SHO with Takahashi FSQ-106ED 106/382 f 3/6 telescope, QHY 600M Pro camera, are 12 shots, 4x300 seconds for each filter, processing with Pixinsight and Photoshop. All data and shots were captured with Telescope Live. NGC 3293 is a bright open cluster in the southern constellation of Carina. it is easily visible just northwest of the large Carina Nebula. This cluster is made up of about ninety stars with a very similar magnitude and particularly compact; the brightest are of eighth and ninth magnitude, while several tens are of tenth and eleventh magnitude. Its distance is estimated at 2327 parsecs (7590 light-years) from the Sun, within the Sagittarius Arm and therefore not far from the large complex of clouds forming the Eta Carinae Nebula; in fact, part of the clouds of this complex lap the cluster, which illuminates and excites them, thus becoming emission nebulae. In addition, the cluster itself would be physically linked to the other objects visible in the area, all related to the large association OB Carina OB1.
A further clue of its belonging to the nebulous complex is its age, estimated at just 10 million years; NGC 3293 contains a large number of blue supergiants, plus a red supergiant. According to some studies, it would seem that star formation in the region of the Carina Nebula began in its northwestern sector, therefore this cluster could be the result of the first formation phenomena that affected the nebulous region; following the formation of this and the nearby cluster IC 2581, the episodes of star formation would have moved progressively southeastwards, until they reached their current position, southeast of the Carina Nebula. According to another study dated 2003, star formation would still be active in the region surrounding the cluster, as evidenced by the presence of some pre-main sequence stars discovered here.
