Bubble nebula

This shot is born from the collaboration with astrophilist friend Mirco Turra , who shot last year with his old Newton 254/1200 double narrow band signal (H-alpha and OIII), to which I added this year the Ionized Sulfur signal (SII) and the RGB stars. I’ve been waiting for a year to build this Hubble palette and we finally did it (I promised her 😅).

The subject of the photograph is the famous Bubble Nebula (classified as NGC 7635, Sharpless 162, or Caldwell 11) in the Cassiopea constellation towards the Cepheus border, discovered in 1787 by William Herschel.
