Perseus is an astronomical simulation software 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 real-time animations. 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 equal or better to other similar programs. Perseus has been packed with many tools, 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. It’s also able to control a remote telescope (10Micron compatible via ASCOM drivers) Perseus Level III offers these further features:

  • More than 15 million objects in its database, telescope control and free upgrades.
  • Opportunity of using the USNO-A catalogue, version 1 or 2, or the UCAC-2 catalogue.
  • Dedicated Script function which allows the creation of lessons and lectures, making Perseus an exceptional learning instrument.
Technical specs
  • Star database: The star database is based on Hipparcos, Tycho, Tycho-II, ACT, GSC, SAO, PPM, GCVS, WDS catalogues, counting 18881123 stars. Includes also HD, HDE, BD, CD, CP, HR, GC names, Bayer’s letters and Flamsteed’s numbers.
  • USNO-A catalogue support:  Visualization of the stars contained in the USNO-A 1.0 or 2.0 catalogue (not included with Perseus)
  • Non-stellar objects database: The database of non-stellar objects is based on Messier, NGC, IC, UGC, PGC-LEDA (maximum magnitude 16), Barnard, Abell, van den Bergh, Sharpless, Monella, etc catalogues, counting 207456 objects
  • Solar System objects: You can simulate the Sun, all the planets and the major satellites. You have also asteroids and comets, based on catalogues available on the internet and updated weekly on Perseus’ site (you can find them also in other sites). You can import data in text format and insert orbital parameters manually. You can filter asteroids and comets using several parameters.
  • Artificial Satellites: You can show on your screen the satellites’ position. You need only to insert the orbital elements in TLE format. The TLE elements are not provided with Perseus because of their rapid variability.
  • Planets and satellites’ visualization: Polygonal texturized graphics, correct representation of shadows, phase, body’s libration and rotation. Detailed surface maps when available.
  • Comets’ visualization: With RealDeep technology, with calculation of tail’s direction and extension (approximated). Comets can also be indicated with symbols
  • Asteroids’ visualization: Represented as stars with the correct magnitude, or as symbols.
  • Stars’ visualization: Maximum magnitude is automatically set according to magnification (customizable); stars are colored according to the spectrum type. Otherwise, they’re white. More styles are available in order to get the desired effect. Contrast between brighter and darker stars is customizable.
  • Non-stellar objects’ representation: Standard symbology is correctly scaled ad oriented. Outline available for bigger objects. RealDeep Technology available for nebulae, galaxies and globular clusters. You can select the symbols you want to see according to catalogues and object’s type.
  • Reference lines: Equatorial, altazimuth and ecliptic coordinates. Galactic equator, meridian and customizable horizon with azimuth graduation. Names, borders and traditional reference lines of any constellation. Double stars’ orbits. Star’s and object’s names (customizable). Catalogue number(s) for any object. Coordinate system, terminator and edge on planets and satellites.
  • Atmospheric effects: Realistic simulation of dawn and sunset; limiting magnitude changes on dusk; refraction is calculated according to temperature and pressure. Local pressure is calculated according to elevation.
  • Refraction: Refraction is computed from the temperature and pressure conditions supplied by the user.
  • Stars and objects info: Coordinates calculated in many different reference systems. Visibility. Names and catalogue numbers lists. Customizable descriptions. Elongation from the Sun and the Moon. References to Sky Atlas, Uranometria, Millennium atlases. Magnitude and spectrum, data on variability, distance, proper motion, apparent dimensions when available.
  • Annotations on the sky: You can add text, fields of view of oculars or films/CCD by defining focal and sensor size (customizable database included). You can track any object in any reference system or relative to any other object. Contacts, entrance and exit time during Sun eclipses are displayed on the tracks
  • Observation tools: Night vision (in red)  – Supernovae maps by Stefano Pesci – Night duration chart – Lunar calendar – Altitudes chart – Guide star search – Instant visibility – Inner planets chart – Calculation of solar and lunar eclipses
  • Telescope control: 10Micron via ASCOM platform, which can control several other telescopes and mount – Meade LX200 telescopes
  • Time controls : Observation time is set as local time, with automatic DST change according to the system’s settings, and manual timezone setting. ΔT and UTC table can be updated via internet. Date visible as D/M/Y, M/D/Y, Y/M/D (by choice). Automatic setting of Julian/Gregorian calendar according to the date of the simulation (customizable to allow for different dates of the calendar reform). Real time animations. You can change the simulation time to the rising/culmination/setting of an object. Time interval -1000/+3000.
  • Automatic calculation of UTC from the local time; automatic DST change according to the system’s settings; automatic or manual ΔT setting. ΔT and UTC table can be updated via internet. Date visible as D/M/Y, M/D/Y, Y/M/D (by choice). Automatic setting of Julian/Gregorian calendar according to the date of the simulation (customizable to allow for different dates of the calendar reform). Real time animations. You can change the simulation time to the rising/culmination/setting of an object. Time interval -1000000/+1000000 (the simulation can give an inaccurate view when far away from historical epochs).
  • Location of the observer Select your location from a database or enter geographical coordinates.  – Ability to modify the location database, and observe from any planet or satellite or from an arbitrary point in space.
  • Printing: You can print in B/W or using customizable colors, add a legend and get a print preview too.
  • Saving and “undo”: Save and load program’s situations using a file. You can redo/undo the last 100 given commands.
  • Image creation: You can save the program’s view using the resolution you want and choosing one of the following formats: JPEG, BMP, TGA
  • Aiming: You can aim at any object existing in the program’s database, independently from reference system and observer’s position, using any object designation recorded in the database; you can aim according to altazimuth or equatorial coordinates.
  • Field of view: Field of view can be set from about 270° to about 1″ (it depends on window’s shape and size).
  • Orientation: You can fix the orientation of the field of view relatively to the horizon, the celestial equator or the ecliptic. You can also set it free. You can keep any object at the center of your field of view.
  • Documentation: Online help is available for any command. Documentation is updated on Perseus’ site. Paper manual is provided with several usage examples.
  • Script : You can take any situation created with Perseus, animate it, add text, sounds and images. Perseus can automatically interpolate two different situations. Script is saved in a unique file. Some more scripts are available on this site.  It’s possible to create AVI movies from the scripts.
