Twitter Facebook Google+, home of the Clear Skies Observing Guides, is offline.

A night under the stars using Clear Skies Observing Guides.CSOG will be back in April 2015, with:

  • CSOG 2.1
  • updated content
  • new styling
  • new Specials: Arp peculiar galaxies, Holmberg galaxies and Stock, Dolidze & Dolidze-Dzimselejsvili open clusters
  • Argo Navis User Catalogs
  • enhanced AstroPlanner planfiles

CSOG will become a free publication.

A heartfelt THANK YOU to all who purchased and supported CSOG in the past two years. Without your support, CSOG would have disappeared long ago and would not have become what it is today: a Modern Day Celestial Handbook.

CSOG will be back soon. Stay tuned.

Clear Skies!
