Sharpless 2-261 from New Mexico and Extremadura (Hubble Palette)

Sh 2-261 is a faint emission nebula located in the constellation Orion. It is named after Harold and Charles Lower - father and son amateur astronomers who captured the nebula on a photographic plate in 1939. It is thought to be some 530 light years from Earth.

This is a combination of data acquired from remote imaging facilities in New Mexico (Deep Sky West) and Extremadura in Spain (e-EyE). The DSW data were captured over several nights between 3 October and 20 November 2017. The Spanish rig is jointly owned and operated with Barry Wilson. Data from Spain were collected between 30 November 2017 and 4 April 2018.

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.
