Observation Session – 30 June 2012

Location: Parc naturel du Vercors, France

Session duration: 2 nights

Sky conditions: Very dark sky (Bortle 2–3), light wind

Instruments:

  • 250mm Dobsonian telescope
  • 100mm apochromatic refractor
  • 150mm Newtonian telescope

Targets:

  • M13 (Hercules Cluster)
  • M33 (Triangulum Galaxy)
  • Mars
  • Rigel

Observation notes:

Transparency improved after midnight and allowed longer visual work on faint deep-sky targets.

The larger telescope resolved dense clusters cleanly, while the refractor was used for wider fields and comparison views.

Members present: Ayoub Berrabeh, Lucille Godefert, Maxime Dallois, Marc Lefèvre
