  • Amazing project i will highly recommend it.

  • This is a great piece of software for logging astronomical observations. Designed towards openness, platform independence, interoperability, extensibility, and usability. I am using ObservationManager on a daily basis and for my specific needs as a hobby astronomer, I would consider it feature complete and a joy to use.
