Description

The Little Dumbbell Nebula is a planetary nebula which, unlike its larger “brother” M27 in Vulpecula, is much fainter.
In fact it is one of the fainter objects in the Messier catalog.

M76 can be found in the constellation Perseus.
Although discovered in 1780, It took until 1918 unil it was first recognised as being a planetary nebula.
The nebula is now classed as a bipolar planetary nebula (BPNe).

Image comments

Some strange artefacts (flares) at the top of brighter stars.
Maybe a bad light frame somewhere in the data that slipped through.
