NGC 247

NGC 247 is an spiral galaxy in the constellation Cetus, and a member of the Sculptor Group. NGC 247 is a fairly bright galaxy (magnitude 8.9) elongated 19' x 5' in position angle 170 degrees. The halo is tear dropped shaped, its northern portion broader and more diffuse and its southern end brighter and pointed. The 9th magnitude star at the southern (lower, in the image) edge clearly lies within the halo. The central area is mottled and brightens gradually to an irregularly extended core. At least seven faint stars are embedded in the halo (hard to count in the image, though). The surrounding star field is somewhat sparse.

NGC 247 is about 12.2 million light years away, and one of several galaxies gravitationally bound to the Sculptor Galaxy (NGC 253, not shown). These galaxies form a small core in the center of the Sculptor Group, which includes NGC 55, 253, 300, and 7793 (all out of scope, not shown). All are late-type spirals, and they form the nearest collection of galaxies outside of our own. Most other galaxies associated with the Sculptor Group are only weakly gravitationally bound to this core.

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.
