Observers First

We made it easier to record observations and now associate them with Sites and Observing Lists, and collect them into Sessions that span hours, or nights.

Graph It

The completely new graph tool will give a quick visual representation of an object’s altitude above the horizon. Essential for planning your night’s observations.

Plan It

Our new updated planner lets you create a list of targets for your observing session with filters like object types, time range, constellation, catalog and more.

Share It

With a free signup you can view & share your observing data from LiveSky.com.** Affordable premium memberships allow for web editing & data management.
