Herschel's Ray / Pencil Nebula

Beautiful colours in this unique looking Pencil Nebula captured over a couple of nights RGB + UHC filter to get additional HA/Hb/O3 signal blended together in Pixinsight (NBRGB script). This is a crop of a wider field which shows some dark nebula matter and other parts of the nebulosity but will at one point take more of the area and see if what results is interesting....

NGC 2736 is a small part of the Vela Supernova Remnant, located near the Vela Pulsar in the constellation Vela. The nebula's linear appearance triggered its popular name. It is about 815 light-years away. John Herschel described this object at its discovery as "an extraordinary long narrow ray of excessively feeble light" in March 1835. This is the expanding debris cloud of a star that exploded cca 11k years ago.

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.
