Description

Unfortunately passing clouds disrupted the light collection process for this image, so that in the end I had to content myself with just 30 minutes of light integration, which however allow for a decent result thanks to the luminosity of the fully open Samyang lens.
Stars are not perfect everywhere: there was an asymmetry somewhere along the axis of the optical path.
