M76 (Little Dumbbell Nebula)

Messier 76 (M76), also known as the Little Dumbbell Nebula, is a planetary nebula located in the constellation Perseus. The nebula lies at an approximate distance of 2,500 light years from Earth and has an apparent magnitude of 10.1. It has the designations NGC 650 and NGC 651 in the New General Catalogue as it was once believed to consist of two separate emission nebulae.

The Little Dumbbell Nebula is sometimes also called the Cork Nebula or the Barbell Nebula. It occupies an area of 2.7 by 1.8 arc minutes of apparent sky, which corresponds to a spatial diameter of only 1.23 light years. The nebula’s size and faintness makes it one of the most difficult Messier objects to observe.

Messier 76 lies in the eastern part of Perseus constellation, next to the border with Andromeda. It is quite easy to find because it is located just south of Cassiopeia’s W asterism and about a degree north-northwest of the magnitude 4.0 star Alseiph, Phi Persei. The nebula is in the same region of the sky as the Andromeda Galaxy (M31).

This image would benefit from more integration so I'm sure I'll revisit it on a future date.

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.
