Perseus is an astronomical simulation program for Windows. It's able to recreate the sky view as you would see it being in any time period and in any place, in Earth or Space. Perseus can represent a truly realistic sky, allowing animations too (both real-time and not). It's based on the most recent star databases, in order to give you access to an enormous amount of data, all easily manageable with a few clicks of your mouse.

Perseus has been realized paying attention to every single detail. We do believe that any other similar program is no match for Perseus, especially regarding the graphics; Perseus is able to reproduce with extreme realism the astronomical phenomena, from nebulae to Saturn's rings. Computation accuracy and precision is truly remarkable: on this subject, usually Perseus has proved itself superior to other similar programs.

Perseus originated from the passion for astronomy and a twenty-year experience as amateur astronomers. It has been packed with many accessories, whose purpose is to transform your PC in an excellent support for your observations. It's able to substitute any paper catalogue or atlas, to help you foresee the sky conditions (clouds apart...) to help the planning and optimization of your observation sessions. All this will be fast, realistic and precise.

Perseus is available in three levels.
Level I is already a complete astronomical software, with more than 15 million objects in its database, telescope control and free upgrades.
Level II adds the opportunity of using the USNO-A catalogue, version 1 or 2.
Level III adds a dedicated Script function which allows the creation of lessons and lectures, making Perseus an exceptional learning instrument.
