Valentine Rose Nebula SH2-174 LBN 598

I had good clear seeing and only had to deal with the normal urban light pollution and a greater than normal "dew" problem due to the recent rainy weather. I did not get all the data I hoped for and will try to get more to add at a later date. I quickly processed the image see what the data looked like and find out if the nebula was even included.

Sh2-174 is an unusual ancient planetary nebula located in the constellation Cepheus at a distance of 980 light-years. At a magnitude of 14.74 it is dim, which makes it difficult to image. It is narrowband Ha and O3 and is processed HOO.

A planetary nebula is created when a low-mass star blows off its outer layers at the end of its life. The core of the star remains and is called a white dwarf. Usually the white dwarf can be found very near the center of the planetary nebula but in the case of Sh2-174 it off to the right. (The brighter star near the center of the blue gas).

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.
