Description

Image taken from the French Alps at 6330 feet of elevation (1930m)

High altitude clouds passing over our head during the acquisitions have scattered the light of the brightest stars; I have not processed that considering that it brings a pretty aesthetic effect

The premises are managed by the association Astroguindaine where astronomers have free access to dobsons during the night and can bring up their own instrument
