Sh2-170 - Little Rosette Nebula

Sh2-170 is a small and faint emission nebula located in Cassiopeia. Stock 18 is a small star cluster in the center of the nebula, which helped me find more information about this target. It seems to be located around 9,000 light-years away from Earth. The nebula resembles the Rosette Nebula, a famous winter target for us in the northern hemisphere, and therefore it's referred to as the little or small rosette nebula.

I went a bit overboard with the integration time on this target, especially when it comes to the HA data, in the hope of getting the faint nebulosity around the nebula. It took most of my clear nights in July and the first week of August. It's also one of the few targets in my field of balcony view that I haven't imaged.

Comments and feedback are, as always, much appreciated.

Clear skies and stay safe!

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.
