Description

According to the weather forecast, I had less than 2 hours of clear sky the night I collected the images, so I had no time to mount a reducer, but in the end the sky remained clear for almost 4 hours :-/. Anyway, even if part of the galaxy are cat off, I'm anyway quiet happy with the result :-)
Ps: Unfortunately some dust corns are visible and the flat frames could not remove them properly :(
