NGC 2736 is a small fragment of the large Vela Supernova cloud that covers 8 degrees of the Southern sky. This nebula covers about ½ degree. Most imagers using broadband filters only have rendered this target as an isolated, or nearly isolated v-shaped cloud (pointing toward the upper right). Those images probably have lead to the popular name “the Pencil Nebula.” As often occurs, narrowband images reveal greater detail and a larger extent of nebulosity, as obvious here. The structure of those surroundings reveals a violent environment characterized by stretched and tangled gaseous streamers.

Although faint, there’s also a pervasive HII, red, background cloud (where the OIII teal cloud does not conceal it). I greatly redden the stars that lie behind it, as is obvious in the lower right.

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.
