By adopting this natural approach to displaying the sky we created a program that is appropriate for absolute beginners and children, yet useful to the most experienced astronomer. It's not only easy to use, it's fun. I heartily recommend it to armchair astronomers as well as to observers. And many experienced observers may find they prefer this display format to the atlaslike appearance of many planetarium programs. The Naked Eye View displays what you would actually see from a variety of settings and conditions.
Stars have accurate colors, twinkle, and dim near the horizon.
Here you can practice star hopping, or just revel in the star clouds of Sagittarius. Click again and you have a Telescope View. For Binary stars a plot also appears showing the orbit with the present separation and position angle marked. For variable stars, a light curve shows how the star's brightness changes with time. Telescopic views of planets show their phase, the rings of Saturn, and the satellites of Mars, Jupiter, Saturn, Uranus, and Neptune.
