M31: Looking down into the core

A detailed view of the core and inner disk of M31 showing dust lanes tracing the inner spiral structure and going all the way to the galaxy core. These dust structures are usually lost in the glow of the bright inner disk and bulge of M31. Also seen in the image is the Hubble's Cepheid Variable (M31-V1) - the Cepheid variable star that was discovered by Edwin Hubble in 1923 (see Revision B). Hubble used that star to show M31 lies far outside the Milky Way, proving it had to be another galaxy and expanding the limits of the known Universe.

This image is a combination of a series of short 20 s RGB exposures taken to reveal the elusive dust structures in the core of M31. The RGB data taken with the 250mm f/4 Lacerta PhotoNewton and ZWO ASI294MM Pro camera over a few hours on November 5, 2023.

Exposure Details:
R: 150x20s (Gain 200, bin 1x1)
G: 103x20s (Gain 200, bin 1x1)
B: 121x20s (Gain 200, bin 1x1)

Total exposure: 2.1 hours

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.
