M76 Little Dumbbell Nebula

Original FITS taken at 2x2 and 3x3 binning for L and colour channels were enlarged by a factor of 3 and 4.5 for deep resolution before stacking and further processing.

The Little Dumbbell Nebula derives its common name from its resemblance to the Dumbbell Nebula (M27).

It was originally thought to consist of two separate emission nebulae and was thus given two catalog numbers in the NGC 650 (south-western part) and 651 (north-eastern part) - see the annotated image.

The nebula is one of the faintest and hardest to see objects in Messier's list.

The bright bar-shaped main body is probably a slightly elliptical ring seen only a few degrees from edge-on. The ring seems to be expanding at 42 km/s.

The structure is classed as a bipolar planetary nebula (BPNe). The total nebula shines at the apparent magnitude of +10.1 with its central star or planetary nebula nucleus at +15.9 visual magnitude.

The nebula has the surface temperature of about 88,400 K, and is approaching us at −19.1 km/s.

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.
