Kohoutek 1-16 (K1-16) Planetary Nebula

Finally finishing off a new DSO. I started capturing this on April 19th, 2022. It's been a rough year thus far with clear skies here and poor seeing. The surface brightness is pretty faint. Even after all my exposure time, I really had to tease it out in processing the data.

Kohoutek 1-16 (K1-16, PK 94+27.1, PN G094.0+27.4) is a planetary nebula in the constellation Draco with a diameter of about 1.6 arcmin and is around 7,000 light year from Earth. The central star of this planetary nebula is a very hot (over 80,000 K) low amplitude pulsating variable star, known as DS Dra. The dominant pulsating period is 28.3 minutes with a semi-amplitude that is usually about 0.01 mag.

To the right of K1-16 near the nebula itself, is a bluish quasar KUV 18217+6419 and is one of the brightest objects of this type in the sky. The distance to the quasar is about 3.4 billion 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.
