You are full of gas and resemble a dolphin’s head….. Obviously you are not of this world!

That’s correct for the object seen here is more than 4500 light years away from Earth, in the constellation of Canis Major. It is basically a space bubble surrounding the Wolf-Rayet star, EZ Canis Majoris, the small blue star in the center and not to be mistaken by the larger orange one to the right, 16omi 01CMa. Fast stellar winds blowing at more than 1,700 km per second from this star, create the bubble-shaped nebula which mainly consist of ionised hydrogen. Sometime in the future, but probably not in our lifetime, the star is expected to go supernova and explode, consuming the dolphin…..

Imaging was done my rig in the remote observatory, Deep Sky Chile. A Takahashi E160 with an F-ratio of 3.3 enables me to achieve a good SNR on this rather faint object and the wide field of view is delivered by a Zwo 6200 full frame mono camera. The Paramount equatorial mount needs no guiding and the Astronomik MaxFr filters results in an image free of halos.

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.
