Sh2-174, Valentine’s Rose Nebula

Sh2-174 is a challenging object to image due to its faintness, but very pretty once you have captured it. This is a 17-hout HOO palette image. I took 3 hours of SII data, but because the SII signal is in the same places as the H-alpha (but fainter), the typical SHO palette isn’t as colorful.The classification of Sh2-174 has shifted over the years from emission nebula to planetary nebula and back again over the years as new evidence of each hypothesis was reviewed. The current position, based on radio imaging, is that it is a planetary nebula that is in the late stages of a interacting with a hydrogen cloud of the interstellar medium. Sh2-174 is estimated to be about 1800 light years away.

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.
