Equipment:

Canon 6D modified with baader filter, Astro duo-narrowband filter , ISO 1600 , 180 seconds

Description:

In this image we have two points to be mentioned: 1) Made with Camera Modify (by removing the Ir CUt Filter and placing Baader Filter, increasing the bandwidth [improving H-alpha uptake) 2) Used a narrowband filter (Dual Narrouband composed of H-alpha and OIII) H-alpha is related to hydrogen capture. Light is created by the hydrogen atom, the main constituent of the universe and the basis of nuclear fusion that feeds the stars. H-alpha is red in part of the light spectrum and contributes to an overwhelming red color in most nebulae Then we have by the two mentioned methods an extreme predominance in H-alpha uptake, showing in red in the central region of the milky way. The orange / yellowish image above and saturn and the largest below Jupiter.
