This is an image I took a couple of years ago and decided to reprocess it. I did not notice the soap bubble until I removed all the stars in Pixinsight. It was really faint and hard to bring it out. I processed most of it using masking in photoshop to bring out the soap bubble. I do better using masks in photoshop that in Pixinsight. I used the Takahashi FSQ 106 and the ASI 1600 mm. This is 20-Ha subs @360sec and 21-O3 subs @360 sec.
