The Topsy Turvy Galaxy (NGC1313) and IFN

This is a field galaxy and a barred spiral galaxy with a diameter of about 50,000 light-years, or about half the size of the Milky Way. It has a strikingly uneven shape and its axis of rotation is not exactly in its centre. NGC 1313 also shows strong starburst activity and associated supershells. It is dominated by scattered patches of intense star formation, which gives the galaxy a rather ragged appearance. The uneven shape, the ragged appearance and the strong starburst can all be explained by a galactic collision in the past. However, NGC 1313 seems to be an isolated galaxy and has no direct neighbours. Therefore, it is not clear whether it has swallowed a small companion in its past. All according to Wikipedia.

I assume that most of the dust in the image is Integrated Flux Nebulosity (IFN) in the outskirts of our Miky Way galaxy and not associated with NGC1313. The IFN would be easy to suppress in processing but I decided to bring it out.

This is LRGB data from Telescope Live at the El Sauce hosting facility at 1500m elevation in Río Hurtado, Coquimbo Region, Chile. It contains 7 x 5 min red, 8 x 5 min green, 4 x 5 min blue, and 12 x 10 min luminosity.

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.
