Sh 2-188 or Dolphin Nebula is a planetary nebula visible in the constellation of Cassiopeia. It lies about 711 l.y. far away from Earth and is about 7500 years old."The expanding gas from the planetary nebula is colliding with ambient gas in the interstellar medium. The nebula is nearly circular in shape but is much brighter to the southeast because the central star is moving rapidly in that direction." -NOAOIt's a weak object, not very easy and requiers long times in exposition and integration.I had a 4 clear night and could acquire about 20 hours light (of which about 15 hours used in integration).HD annotated version https://adobe.ly/3AgOh8iHD SHO (Hubble Palette) version https://adobe.ly/3UTAnRpHD HOO (Bicolor) version https://adobe.ly/3EyDvwO

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.
