Andromeda and the OIII Flower
The OIII “flower”, as some have come to call it, is an extremely faint OIII structure that is only visible after considerable integration and careful continuum subtraction. After 25.5 hours of OIII integration I could just barely see the flower. I’m happy I could see it but given how noisy it is I’m happier with the version of this image without OIII.
