NGC 896 The Fish-Head Nebula

This is a Hubble-Palette SHO image, but I have added RGB stars following the same procedure, passing through the CIE L*a*b colour-space, that I used for the first time on my image of Melotte 15. It's hardly visible in this image becasue most of the stars are white.

This object (also called W3 in the 1956 Westerhout catalog of radio sources) is just to the north-west of the Heart nebula (also called W4). The dark dust streak separating the object gives it the appearance of a fish, with the part to the west (right in this image) being the head, NGC 896, while the eastern part is the body and catalogued as IC 1795. For this reason NGC 896 is sometimes called the Fish-Head Nebula.

Close to the brightest star in the fish-head is an area only visible in the infra-red where a group of massive stars are still in the process of formation, accumulating gas from the cloud they have formed in.

The brighter NGC 891 was discovered by William Herschel in 1796.

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.
