Why do the sky backgrounds of my pictures vary so much between the types of objects?
Our proprietary image processing algorithm applies different parameters for each object (colorimetry, saturation, histogram …). That’s why you can see rendering differences between your photos of clusters, nebulae or galaxies. The quality of the photos also depend on the observation conditions (temperature, light pollution, transparency of the sky, turbulence …) and the level of difficulty of the star (magnitude…).
Our software is constantly evolving and updates are regularly made to improve the image processing and to refine the quality of the photos. You will quickly see tremendous progress in this area!
