Sh2-170

This beautiful, delicate object is an emission nebula located 7500 light years away in the Cassiopeia constellation at a declination of +65 degrees. The image was processed using the HOO palette and RGB stars.

The nebula is dominated by hydrogen gas, although some oxygen is also present as indicated in the whitish glow towards the core of the nebula. The open star cluster in the center is Stock 18.

The nebula is about 20 arc-minutes in diameter, which corresponds to an actual size of almost 50 light years. It has the nickname of the Little Rosette Nebula.

The dark dust areas in the outer region of this nebula are interesting, especially towards the bottom.

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.
