Sh2-170 - The Little Rosette Nebula

Originally selected as a SHO target during the last full moon cycle and just enough time was devoted to show there is quite a bit of structure within the nebula. More time, especially SII, would definitely benefit the details. A bit of pushing the SHO color palette was made to help this frequently ignored DSO to stand out as worthy of making a target list.

The Little Rosette Nebula (Sh2-170, LBN 577) is an emission nebula in Cassiopeia about 7500 light years distant. It lies within the Perseus arm of our galaxy. In the nebula center is Stock 18 - a small, young cluster of stars. (Baerenstein Observatory)

Image taken over several nights: Sept 19, 23-26, 2021.

Although this nebula is listed in Lynds Catalogue of Bright Nebulae catalog, it is generally perceived as a somewhat dim nebula. It is brightest in Ha, dimmer in SII and very dim in OIII (center only). No signal was seen in SII or OIII in three minute individual frames.

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.
