Description

After looking for it for four nights, including a lift at three in the morning, finally on May 25 at sunset from a hill where you could see the sea in the North, found it immersed in the twilight light just 8 degrees above the horizon . It was setting but I managed to take 24 poses. There was no trace of the false nucleus or of the tail. My friend Michael Faigenbaum, who saw an unprocessed frame, can confirm the absolute inconsistency of the comet, of which only a faint diffuse light was perceived. The main difficulty was the stacking that I had to do by calculating the shift in pixels, between the first and the last shot, in the unit of time elapsed between the first and the last image. The end result has nothing to do with the fantastic photographs taken from the southern hemisphere due to the turbulence and the glare present at those small heights. However, I am still very satisfied in having immortalized, perhaps for the last time the swan comet from the Northern Hemisphere.

Clear skies to everyone, Gabriel.
