I was interested in this object for a while. Not much pictures around except those wide angle shots from NGC 2070.
Henize 70 is a faint interstellar gas bubble. The luminance channel did not brought it up so i had to use the Ha filter with more exposure time. The bubble measures about 300 light-years in diameter. It was created by winds from hot, massive stars. and supernova explosions and the interior is filled with tenuous, hot expanding gas.
