56 million Light Years away in the constellation Fornax (Latin for furnace), this behemoth of a barred spiral galaxy has a central supermassive black hole of around 2 million solar masses that rotates at near light speed. With a visual magnitude of 10.3 this giant Seyfert-type galaxy is around twice the length of our own Milky Way galaxy. The bright centre of the galaxy is thought to be due to huge amounts of superhot gas ejected from the ring of material circling a central black hole. Young luminous hot stars are being born out of these interstellar clouds and they give the spiral arms a prominent blue colour. The bar and spiral pattern rotates with one full turn every ~350 million years. Thus NGC 1365 has rotated around 60 degrees since the Eocene-Palaeocene time boundary on earth, which is when the light for this image started its journey from NGC 1365 to earth.

This is about as far as I can go with this image, my first attempt with a (presently) unguided mono ZWO ASI1600 Pro cam and 30 minutes of unbinned (1x1) luminescence data (30 sec subs) plus 10 minutes each of ZWO's RGB 36mm filters (20 sec subs). The 3 colour channels were binned at 2x2 in order to quickly paint the higher resolution luminescence data.

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.
