Sky Tonight – The New Stargazing Tool

With Sky Tonight, you can explore the sky at your own pace and with your own interest. It’s a brand new stargazing tool that allows you to customize your observatory experience.

You can set the time to begin your search and the object to view — any space object that interests you. You can also make an alarm for any space body configuration, explore the unique relative to observer trajectory, set a magnitude limit to filter out space objects, and much more.

Using the unique, customizable tool, you can view the sky anywhere at any time. Set the time to begin your search and the object to view — any space object that interests you. You can choose to view objects with different ranges of brightness, magnitudes, and time. The brightness can range from the faintest stars to the brightest supernovae. When searching, you can view only certain objects.
