NGC1313: The Topsy-Turvy galaxy

NGC 1313 is one of my favourite galaxies. A beautiful barred spiral, that has been spectacularly disrupted by a galaxy collision in the past. Not unlike a more distant version of the LMC, although in this case the other galaxy is nowhere to be seen.

Found some old Chilescope luminance data [1.25hours worth] to which I added 12hr of LRGB + Ha data I had been collecting in the latter parts of the night with my RC8. Required a bit of a tricky combination to not destroy the detail in the Chilescope L data, while preserving the additional depth provided from the RC data. I have also include a starless version, just to show the extended nature of the disrupted galaxy. I do like the way this image shows different colours on either side of the galaxy, most likely caused by differing amounts of dust extinction.

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.
