NGC3293

NGC3293 is an open cluster situated with in the larger Carina Nebula Complex of gas and dust clouds and is around 9000ly (2750pc) in distance from Earth. The cluster is 26.4ly in diameter and contains over 100 stars, the brightest of which are blue supergiants of 6.5mag and 6.7mag. Most of its over 100 stars shine brighter than 14mag. The cluster is also notable for its pulsating red supergiant V361 Carinae. Studies of the stars have found that the cluster appears to have formed over at least a 15-20 million year period. The bluest of its stars appear to be around 6 million years old, whereas the redder, dimmer stars seem to be around 20 million years old. So, there was either a long continuous burst of star formation in the cluster, or, there was possibly two episodes of star formation. The cluster was discovered in 1751 by Nicolas-Louis de Lacaiile in his star survey from Sth Africa.

Surrounding the cluster is a vast field of gas and dust clouds associated with the Carina Nebula, much of which still remains hidden within the pic and I'll bring that out later with extra subs. In any case, the pic also contains the very prominent Gabriela Mistral Nebula (IC2359/Gum31), at the upper right of the pic. Located 7560ly (2317pc) from Earth, it lies between us and the cluster. Within Gabriela Mistral is another open star cluster, ngc3324. It has an apparent magnitude of 6.7mag and is around 6.754 million year old. Most of its stars are also hot and blue.

Pic was taken with t68 at the Bathurst Observatory (BAT-iTelescope Network), 15x60sec subs.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
