NGC1365 - Great Barred Spiral Galaxy (Chris Jensen)

NGC1365 - Great Barred Spiral Galaxy

My first galaxy image with my new Edge HD8, and it has been a battle to capture the data for this one. I bought the telescope at the end of November last year, and as usual, summer has been horrible for imaging in South East Queensland, Australia. Ideally, I wanted to get another 4 hours of data but it looks like the weather is going to conspire against me, so I have processed what I have.

From Wikipedia
NGC 1365 is a large barred spiral galaxy in the Fornax cluster. Within the larger long bar stretching across the centre of the galaxy appears to be a smaller bar that comprises the core, with an apparent size of about 50″ × 40″.=10.5px This second bar is more prominent in infrared images of the central region of the galaxy and likely arises from a combination of dynamical instabilities of stellar orbits in the region, along with gravity, density waves, and the overall rotation of the disc. The inner bar structure likely rotates as a whole more rapidly than the larger long bar, creating the diagonal shape seen in images.The spiral arms extend in a wide curve north and south from the ends of the east–west bar and form an almost ring like Z-shaped halo.=10.5px Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole.NGC 1365, including its two outer spiral arms, spreads over around 300,000 light-years. Different parts of the galaxy take different times to make a full rotation around the core of the galaxy, with the outer parts of the bar completing one circuit in about 350 million years. NGC 1365 and other galaxies of its type have come to more prominence in recent years, with new observations indicating that the Milky Way could also be a barred spiral galaxy.

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.
