M83 The Southern Pinwheel in Hydra...

This galaxy is in the group that includes Centaurus A and lies about 15 million light years away. It is about 1/2 the size of the Milky Way and does contain a good amount of new star birth regions. It also has a double nucleus which may be the result of a galactic merger long ago.

The above information was obtained from messier-objects.com.

This one was a little bit difficult to do and the quality suffers because of the fact that it only rises 27 degrees above the horizon at transit. I also had some difficulty with my calibration files. I may have shot the galaxy at a different gain by accident. I have re-done the calibration images several times to no avail. So unfortunately, I am leaving some data on the table so to speak. I do think this is worth revisiting next year but in March or April rather than May.

I knew it would be a little more difficult because of the lack of elevation above the horizona but I wanted to do this anyway to see what would happen and because these barred spirals are very interesting to me.

Anyway, I hope anyone who views it believes it was good enough to publish. Comments and/or criticism always welcome.

CS to everyone!

Mike

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.
