Messier 27, also known as the Dumbbell Nebula, is a famous planetary nebula located in the constellation Vulpecula. It lies some 1,360 light-years away from Earth. It is one of the most well-known and studied planetary nebulae in the night sky. It was discovered by Charles Messier back in 1764.

The colors shown in this image come from the emissions hydrogen (see in red) and oxygen (see in blue) emissions. All the data needed for this image has been captured from my backyard observatory located in Prades (Tarragona) with the use of narrow band filters and also R, G, B filters to capture the colors of the stars. The color mapping of the nebula is a HOO, where Hydrogen Alpha is assigned to the R channel, while the [OIII] is assigned to G and B.

The full image covers an area of 27' x 29'

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.
