Observation Manager is a free and open source logbook for (amateur) astronomical observations. All logbook entries made in Observation Manager are stored in the free and open OpenAstronomyLog XML Schema. Log your observations and make sure next time you're searching for an celestial object you can make benefit of your past observations! Observation Manager comes with four catalogs of astronomical objects (Messier, HCNGC, Caldwell, Solar system, GCVS 4.0) and if you miss an object, just add your own entry!
