Remnants from a star that exploded thousands of years ago created an astonishing spectacle seen here. Officially known as NGC 2736, it is part of the huge Vela supernova remnant and its linear appearance triggered its popular name, the Pencil Nebula. The nebula's shape suggests that the shock wave which followed the star explosion encountered a region of dense gas, causing the nebula to glow and appear like a rippled sheet. Some regions are dominated by ionized oxygen atoms which glow blue in the picture, yet other regions ofmostly hydrogen and are seen emitting red in the image….

Close to 33 hours were utilised to capture the data on my telescope installed in the Deep Sky Chile observatory. Dark skies with good seeing, a fast scope and modern sensors make easy work of capturing pristine data with very few lost subs. I deliberately captured a lot of data on Oxygen III and Hydrogen Alpha to better illustrate what is mentioned above. Image processing has progressed leap and bounds in the last year and with the myriad of post processing tools now available, constructing the final image was an easy task.

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.
