With the many gathered nice Integrated Flux Nebula shown, the object looks a bit dirty. That's why the image does not look smooth after blending with Ha and O3.

-----------------------------

SH2-174 is a planetary nebula visible in the constellation of Cepheus.

It is one of the northern most planetary nebulae of the celestial vault; γ Cephei is located about 3 ° north of Alrai and is visible in long exposure photos taken with a powerful amateur telescope. Its strongly northern declination means that it can be observed almost exclusively from the northern hemisphere, where it is circumpolar up to tropical latitudes.

The cloud, cataloged as a generic emission nebula in the 1960s, has never shown signs of star formation in progress, nor was the ionizing star of its gases known; during the nineties the hypothesis was advanced that it was a planetary nebula, whose central star has over time slipped out of the gaseous envelope it created itself, given that its dimensions were too small to be an H II region, but comparable to those of a normal planetary nebula. This ionizing star would be the white dwarf cataloged as GD 561, located outside the cloud. The distance, from which the dimensions were derived, was obtained through the study of the radial velocity, and is indicated around 300 parsecs (about 980 light years).

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.
