CyberSky CyberSky displays accurate charts of the sky as seen from any location on the earth. Sky charts can include stars, constellations, deep sky objects, and solar system objects, and can be enhanced by the addition of labels, coordinate system grids, and reference lines. CyberSky's user-friendly interface allows you to easily change your view of the sky, search for celestial objects, and display data about those objects. CyberSky also prints attractive sky charts that you can take outside with you. Shareware

Deepsky 2000 DeepSky 2000 quickly generates detailed lists that are easily optimized, and even creates finder charts of those objects if you so wish. In particular, the 3 panel finder charts showing different field of views is an excellent idea which makes locating objects at the telescope a piece of cake. It doesn't stop there - the observerís logbook makes life so much easier in recording and cataloguing your observations Commercial
Deep-Sky Planner Deep-Sky Planner is an easy-to-use astronomical observing, imaging, and photography planning tool. It helps you prepare for your time at the telescope by creating reports of objects from its 10 deep-sky and 3 stellar catalogs that meet the search properties that you specify. It is also useful to the solar system observer, providing solar, lunar, and planetary ephemerides, times of astronomical darkness, and dates and times of planetary phenomena. Commercial

dObjects 1.7 dObjects is an astronomical database and observing log program which runs under Windows 95 and Windows NT. It includes a database of over 34,000 astronomical deep-sky objects. In addition to the standard observing information about the objects, dObjects' database includes references to popular astronomical magazines, books, and internet resources, information you have about objects within your computer, and the Internet. A Web Services feature lets you view the digitized Palomar Sky Survey easily, and communicates with other servers keeping you up-to-date on the most recent web references to objects. An extremely flexible means of object selection, sorting, and reporting make dObjects the ideal tool for planning observing sessions, logging your observations and finding information about the objects of interest to you.

Find Orb FIND_ORB is a user-friendly program that handles the initial determination of the orbit using the method of Herget. Given some more observations, it can find a "best fit" orbit using the method of least squares . It's sufficiently bright to include the perturbing effects of the planets and Earth's moon, and may eventually include effects of Jupiter's four largest moons, Titan, and of the first four asteroids. Freeware
Guide V7 a powerful general-purpose charting/desktop planetarium tool. The main purpose of this program is star chart generation, and it is unsurpassed in this area; but it also provides immense amounts of data on the objects displayed, ephemerides, telescope control, and other useful features Commercial

Luna Occultation Workbench LOW is there for anyone, such as you, who is interested in computing predictions of occultations by the Moon of the 8 major planets and the 53.920 stars (21.8% of which are Hipparcos stars!) listed in the XZ94F star catalogue. In addition you can record your observations and send them by email to be reduced by the International Lunar Occultation Centre in Japan. You can, among many features, also view the Moon and the planet or star as they would appear at the time of occultation. The moon's phase and even the colouring of the moon due to the Earth's shadow during a lunar eclipse are taken into account! Over the last year LOW has become the world's defacto standard for predicting and recording lunar occultations. Join the ranks of many happy users and download it! Freeware
LunarPhase LunarPhase is a utility for Win 95/98/NT which provides a range of information on the Moon and, to a lesser degree, the Sun, graphically displaying the current phase of the moon (in real time). It uses the user's geographic location, Timezone and Daylight Savings Time (set on the Configuration screen) for its calculations, so these must be set up correctly. All times displayed (and printed) are in local time. Shareware
MegaStar MegaStar was the first software to integrate the Hubble Guide Star Catalog, and combine it with a massive deep sky database of 84,000 objects. We were the first to implement the "eyepiece view," with deep sky objects plotted to scale and galaxies rotated to show position angle. MegaStar set a new standard back then, and still remains the premier charting program for data accuracy, functionality and user-friendliness. Commercial

Moon View 3 allows you to view the Moon and a celestial object as it will appear from your location. Simply enter the date, time, your position and the position angle at which the star or planet is occulted, and MoonView will render an image of the phenomenon. MoonView takes the Moon's librations into account and can also display the eclipse phase during a lunar eclipse. System requirements: MoonView also is a 32-bit program and thus requires a PC running Windows 95, 98 or NT, 4 MB of RAM and at least 1 MB of disk space. Freeware
