Observation Planner

Kristian Ivanov

Since KDE SC 4.4, Prakash Mohan's GSoC work has been released in KStars. KStars now has an awesome observation planner to plan your observation sessions. The execute session option allows you to log information about objects as you observe them. Alternately, you may also write a short log in the session planner itself. We wish you a lot of fun planning your observations with KStars!

You can even add some pictures to the objects. The image list is a Google image search list. To add image to an object all you need to do is press Find Image button on the right and then find an image that you like. If you do not have an Internet connection you can open an image from your hard drive. Note that images that will be used are going to be cropped to 600x600 pixels.

The first way of doing this is by pressing Ctrl+2 or Ctrl+L to open the Observation List, then press the Add Object button.



The Save all Images button does a search for the SDSS images and displays the DSS image if the requested RA/Dec is out of the SDSS footprint.


This is an SDSS image of a galaxy



This is an DSS image of the same galaxy


The Delete all Images button does the opposite. It deletes all downloaded images.


The image for the galaxy is now deleted


You can add more objects by pressing the Add Object button. It has quite accurate method for sorting out items, depending on what options you have given to him. They are: Any, Stars, Solar System, Clusters (Globular and Open), Nebula (Gaseous and Planetary), Galaxies, Comets, Asteroids and Constellations + the name filter.

Here you can see the object visibility based on the time and date. The leader line shows the time right now.

And below this you can add notes about observing this object.

Do note that the Wish List is not the Session Plan. In the Wish List you can add objects that you wish to observer at some point. From there you can add them to the Session Plan.

You can see the pop-up window that comes after right-clicking on an object.

Here is the second way of adding objects in your Observation Plan and using you Observation Plan. To use this way you just need to press the 4-th icon on the top-left corner of the Observation Planner Wizard (which is highlighted with yellow).

Despite looking differently this way is basically the same as the first one. Although that it could be a bit more detailed. Here you can see the same categories of objects.





You can choose where these objects to be on the sky. There are four options available for you: All over the sky (which is the default option), by constellation and in a region (rectangular or circular).



You can choose the date for the observation and the place you are going to observe from.



You can choose the treshold of magnitude for the objects to be shown. In astronomy, absolute magnitude (also known as absolute visual magnitude when measured in the standard V photometric band) measures a celestial object's intrinsic brightness.



You can save your observation plan. And it will save it with a .obslist extension.



You can also access the WUT (What's up tonight), which could be of a great assistance to you. It can give you ideas what to observe on a date, time and place that you specify using the configuration buttons int the top-right corner of the What's up tonight window.



This is how the Execution Session Window look. It can be opened by pressing Ctrl+2. In it you can also see some information about the selected object and you are able to add observing notes.


First Execute Session window


By pressing the Next Page button you will access the second page of Session Plan. Here you are able to see information not about your object, but about your equipment.


Second Execute Session window


Pressing the Next Target button will cause the Execute Session to open the first window about the next object.
