Hi all,

A few weeks ago, I decided to retake an image of the Bubble Nebula (NGC 7635, the previous one had been taken in 2016). This time, I was able to take a deeper image, adding also SII as one of the narrowband filters employed. This nebula is very attractive because of the geometry of the massive O6.5 star (whose bowshock creates the bubble when interacting with the surrounding nebula), producing a clear 3D effect. This effect is more pronounced when color mapping the frames to a modified Hubble palette. You can find this image, in both color palettes (Hubble and natural) as well as more info at:
