M83 - Southern Pinwheel Galaxy

First, I would like to thank Mark and his pup Auggie who graciously let me set up at his home alongside a small local outlying airfield. Without his hospitality and willingness to host me, this picture would not have been possible from my home and would have been far more light polluted if I had gone somewhere else.

Second, I discovered that the cooling fan on my camera had been giving me elongated stars at long focal lengths (1480mm+) due to its vibration. This photo was taken with cooling turned off on my ASI 533MC Pro and the stars were much better in this shot than others. BlurXTerminator was also more effective at resolving the image in post processing without fan vibrations. Surprisingly, the effects from lack of cooling did not seem as drastic as I had anticipated and seemed to be easily callibrated out with darks.

I hope you enjoy!

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.
