Observation Session – 01 December 2012

Location: Plateau de Valensole, France

Session duration: 2 nights

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

Instruments:

  • 250mm Dobsonian telescope
  • 7×50 binoculars
  • 100mm apochromatic refractor

Targets:

  • Rigel
  • Betelgeuse
  • M42 (Orion Nebula)
  • The Moon

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.
