  1. Yesterday we visited the #Volkssternwarte #Köln ✨🔭 The weather was overcast, so conditions were limited, but we were still able to observe #Jupiter and its four #GalileanMoons #Io, #Europa, #Ganymede, and #Callisto.

    The main #telescope is a 600 mm #Cassegrain reflector with a focal length of 5,400 mm, which enables high-magnification observations of #planets, the #Moon, double #stars, and bright planetary #nebulae.

  9. 📸 Rubin’s First Look: A Sagittarius Skyscape
    This wide-field view from the new Vera C. Rubin Observatory spans over 4 degrees in Sagittarius. It captures the Lagoon Nebula (M8) and Trifid Nebula (M20), two iconic regions of star formation in the Milky Way.
