  • Hybrid combination of Narrow Band (SII-Ha-OIII) + LRGB of the Nebular Complex NGC 7635 in Cassiopea, also called "The Bubble Nebula". The Narrow Band filters help to increase the fine details visibility, the LRGB contribution, smooths the image without affecting the details visibility.

    Interesting Facts:
    - NGC 7635 is a big and bright Nebular Complex in Cassiopea. In the central part of the nebula, there is a very curious object that looks very similar to a cosmic bubble.
    - The "bubble" is made of gases which are expanding under the strong pressure of the stellar wind produced by the very hot and massive star SAO 20575. This star is the brightest star in the nebula (the one with the spikes) and it is not in the center of the nebula.

    Image acquisition: M.Angelini-F.Antonuci-F.Tagliani
