Tiny Planetary Nebula PK 131-5.1 in Perseus

PK 131-5.1 is a planetary nebula in the constellation Perseus, not far from the border with Cassiopeia. It lies near enough to the Double Cluster (NGC 869 and 884) that it may appear in some widefield photos thereof. Spanning only 24 arcseconds, it shines at about 15th magnitude.

This is an HOO bicolor narrowband image at f/7 and 2000 mm focal length taken with the C11 EdgeHD. I have been imaging planetary nebulae recently, and I needed an early evening target after finishing M76, so this rarely seen DSO got the nod. 105 minutes of integration time from the sharpest subs were used for the luminance channel, so it is somewhat noisier than expected for the total integration time listed. With tiny DSOs like this one, good seeing and low FWHM are a must, so I sacrificed a lot of subs for better focus. I also did not apply any noise reduction in order to avoid blurring out what little detail there is.

If I imaged this one again, I would try shooting it at f/10 and binned 1x1 just to put more pixels onto it.

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.
