M83 Southern Pinwheel and Surrounding Galaxies

Will be the last galaxy for me of the season. Very very low in the southern sky for me, never getting higher than 29 degrees in the sky. I was surprised at the amount of Ha signal in the galaxy and then pulling the catalog I was no longer surprised. Very heavily catalogued and studied!! Something that popped out when i was doing the Continuum Subtraction was an odd object with a shadow in the middle of it. Turns out it is the core of PGC48287 so I am leaning to the side that that is real structure I detected! PGC4867 had some nice dots of Ha in it too. Finally there is a bright Quasar, QSO B1333-298, with a Z shift of 1.9 putting it at a comoving radial distance of 16.7 billion light years!

Hope you all had a successful galaxy season!!

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.
