lets amateur and professional astronomers make their sky observing sessions much more productive. Deepsky comes with a searchable, browsable, spreadsheet-style database of over 400,000 deep sky objects. It can display 18 million stars (to a magnitude of 15.5) on a star chart. It comes with an observing planner and an observing logbook.
Deepsky contains detailed information about the solar system (including the Sun, Moon, Planets, Comets, and Asteroids), and it can process images.
If you own the LX200, AutoStar, or Nexstar Telescope, you can use Deepsky along with a laptop to control it. Deepsky is also integrated with the Internet, giving you access to the Digital Sky Survey, Sky Rover Sketches, and NGC On-line.
