Sh2-174 - The Valentine Rose Nebula

This is my first planetary nebula and, at 41 hours, the most time I have spent on a single object.

In researching this nebula, the white dwarf responsible for it has an unusual relationship with the surrounding nebula. One theory holds that the white dwarf is merely passing through the gas cloud and is actually several times older than it. Supporting this theory is the fact that the speed of the white dwarf is different than that of the ionized gas.

I started this project with intent to do something different than the usual galaxies and nebulae I have been imaging and was pleased at the final result. This object is fainter than I expected it to be and the modern processing tools developed by Nikita Misiura and Russell Croman were enormously helpful in the processing. One really cool thing about this field is that, being close to the pole, you can pick out several small and distant galaxies even in a narrowband image like this.

It is funny how these things work out: when I purchased my ONTC 808, it was with the intent of getting more images faster than I could with my previous small refractors. Instead, I find myself spending more time and going deeper on fainter objects.

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.
