Image Description and Details : Here is my first object captured in 2020.
This is the dolphin head nebula, Cataloged Sharpless SH 2-308, it is about 5,200 light-years from home towards the constellation of the Big Dog.
The massive star (Wolf-Rayet type) that created the bubble is the bright star located near the center of the nebula.
It generates a powerful radiation which drives out the gas around thus creating a giant bubble.
