NGC 247

NGC 247 is an Intermediate or Dwarf spiral galaxy about 11 million light years away in the constellation Cetus. It is a member of the Sculptor Group of galaxies, one of several that are gravitationally bound to the Sculptor Galaxy (NGC 253). This is one of the nearest groups of galaxies to the Milky Way. This is a large (21.4x6.9 arc minutes), bright (mag 9.9), and detailed galaxy but it lies low in the sky for my latitude, reaching a maximum elevation of only 30 degrees. This makes it difficult to get a quality image because the low elevation means that my telescope will be peering through a huge amount of light-scattering atmosphere, dimming and blurring the image. That said, the size and detail in this object demands that we give it a try.

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.
