NGC 247 LRGBHa

NGC 247 is a fine example of an intermediate spiral galaxy showing some nice features and a smattering of Ha dusted around the spiral arms. The galaxy is located approximately 11.2 million light years away in the constellation of Cetus (the Whale) and is part of the Sculptor Group. The size of the galaxy is estimated to be about 70,000 light years across which makes it somewhat smaller that our home galaxy, the Milky Way (with a diameter of approximately 100,000 light years). The galaxy has a quite noticeable distinguishing feature in the form of a void leading to a common name of the "Claw" galaxy.

The Tak TSA120/QSI683 combination used for this project is not what one would call a galaxy hunter due to the 1.5 degree field of view. It is ok for some galaxy fields though and particularly with this one given the nice array of background galaxies present in lots of interesting shapes and sizes.

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.
