Whew, this is a tough target, over 2 nights I captured just under 14 hours, but I am not sure the 7 hours I captured the first night helped. I had just upgraded to the new ASIAir Beta version and did noticed it changed my gain to 50 and for some reason my dithering did not work. Plus the 1st night I took 3 and 5 minute exposures. the 2nd night I increased my gain to 100, dithering worked, lowered my temp from -10 to -20 and I captured 10 minute exposures. When I stacked my image, the 10 minute stacked images looked better than the 2 night combined stack, the combined stack actually had less detail. So I ended up just layering the image from the first over my 2nd night image as a Lum layer.

Sh2-174 ranks as the most northern Sharpless objects at 81 degrees north. There is not a lot of information about this Planetary nebula; although it was discovered fairly recently and identified as a Planetary nebula in the 1990s.

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.
