Details:
The green ray of the brightest star in the sky.
Around mid-May, Sirius reaches the western horizon and sets in the twilight lights.
In the first part speed x8.
This is the best time to try to admire its sunset and the play of colours it creates with the atmosphere in a still bright context.
Here it is taken through a 12" Dobsonian telescope at 76x, as it sets, less than 4° from the horizon, next to a pine tree more than 1.6km away from the observation point.
I took a video with a Huawei p30 Pro smartphone visible on my website.
