on the evening of july 20th I had another chance for Neowise, and knowing its huge tail I choose Sigma 180mm and Eos6d to record as much as possible. The coma now had turned distinctly greenish, and the blue Ion and yellowish dust tail make for a colorful appearance.

Eos6da at Iso 800, 166x15sec shots at f/2.8 - comet and stars were stacked separately and reunited.#

Here is a video made from the raw frames, covering the comets motion during the 40min session
