I promised another post when these new bubbles had been confirmed. Three astrophotographers, Andrealuna Pizzetti, Tel Lekatsas and Christian Sasse have, independently, taken Ha pictures of this region, in order to try to confirm the existence of this bubbles. The integration of all their 19x600s images (see image here), taken with another 20″ telescope, shows the same bubbles’ position and shape, confirming them.
Next step will be the process of trying to get this nebulosity registered in any kind of catalog. I will keep you posted.
