Stellarium Web

This is a new web based version of Stellarium which is still in the development stage so it will be hard to keep it up-to-date.  The features are currently far less powerful than the version you can download but if you are in a pinch, this will have to do.

You can find Stellarium Web at : https://stellarium-web.org/

Here is a very brief overview of what you can do.  When you open the site, you will be asked to use your current location.  The screen will show your sky if it is night but if you open the program during the day, the program will take you to the night of the current day. 

 Below are some of the features of Stellarium Web (which are all found in the downloaded version but found in different ways).  I've changed to a day view so it is easier to read.

Zoom IN or OUT:  The only way I've found to Zoom IN or Zoom OUT is by using the scroll feature on my mouse.  However, if you search for an object, two zoom buttons appear (Plus and Minus) which allows you to get change your field of view (FOV)

Moving in Time: When you click on the time controls, this menu pops up.  You can change to any time you like but the nice feature is the sliding bar that lets you view the sky changes at faster rates (you can also change time in increments using the up/down arrow)

Centering objects on the screen and locking them:  When you open the program and run forward or backward in time, the landscape is fixed and the sky moves.  However, you can lock a selected object and as time moves, the selected object remains fixed and centered on the screen.  Simply search for an object and once it is found, the program automatically locks it in the center of the screen.  In addition, if you simply click on any star or planet, an icon that looks like a circle with a star in it appears (along with some information about the object you selected).  Click on the icon and it becomes the centered fixed object and time runs on.  The only way I've found to undo the lock feature is to reload the program.

Some important lines - the Meridian and Ecliptic

In the upper left corner of the screen is a menu that lets you draw two important lines in the sky.  Both the meridian line and the ecliptic are found under View Settings.  Please make sure you can do this.

As stated before, this version is somewhat limited when compared to the download version but if you master all the features I've covered you will be fine for the evaluation. 

One of the feature in Stellarium Web I have not found is a good help menu.  If one becomes available, please let me know.
