Mini Sculptor Galaxy NGC247

NGC 247 is a relatively small spiral galaxy with a diameter of 70,000 light years. It's located approximately 11 million light years away in the Sculptor Galaxy Group which has 13 members. One of the peculiar properties of this galaxy is the apparent "void" in the spiral arms which can be seen on the right hand side. It is thought that the stars in the void are “significantly” older than the ones outside it, with the birth of stars in this region slowing down for some reason, having not taken place for around a billion years.

Despite being on my target list for ages, this galaxy always seems to get bumped to the next year due to limited imaging time and other targets. So it's pleasing to have finally captured this charming galaxy, along with its multitude of distant background galaxies.

I had to forego the addition of my Ha data due to tracking issues, but hope to blend some in down the track. I had intended to hold this image in staging until then, but eventually decided to post the LRGB anyway.

Thanks for looking, and clear skies.

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.
