Second part of this magnificent region. Although I am happy with the result I have not been able to reflect my intention to define the Soap Bubble Nebula, I intuit that for that I had to exponentially increase the exposure in OIII in the six panels because my intention is to make a mosaic of six panels. Maybe next time.
Greetings to all friends, I hope you enjoy it.
