Comet C/2020 F3 (NEOWISE) on Jul 14, 2020. Colors of the gas tail.
In this image a point in the gas tail has been used for white balance. The colors in the gas tail come from different elements, but not from Sodium because an Light pollution filter had been used which blocks wavelength between 540nm and 645nm.

Color factors relative to the images above (white balance using the stars) are 3.9 for red and 2.2 for green. Colors have not been mixed (no saturation enhancement because red channel became to noisy).

Images are aligned to comet. Total exposure time was 60 min.
