🔭 I am a Live Planetarium Presenter – “Planetariumist” – at the Fresh Air Fund’s Gustafson Planetarium at Sharpe Reservation in Fishkill, NY. We Planetariumists are learning to use Stellarium scripts. This article will teach you how to use a Stellarium script to quickly load the art images for the 13 Zodiac constellations:
Aries Taurus Gemini Cancer Leo Virgo Libra Scorpius (Ophiuchus) Sagittarius Capricornus Aquarius Pisces
Online Camp programs for Astronomy Education
Like every other camp program during COVID-19 times we have had to move the live shows to an online format. In our case we are doing zoom astronomy presentations for the campers. It’s been a great experience to learn how to do quick and entertaining astronomy shows online and I wanted to share a few tips to make better astronomy online presentations.
Stellarium Scripts for Astronomy Zooms
I want to make Stellarium really work for online presentations like zoom astronomy outreach, so I figured out how to write scripts to control it. To get started, I just copy-pasted and modified an existing script that did something like what I wanted it to do.
Stellarium scripts help you do the tedious set up and configuration steps. There is no need to open windows and drag and click around while your audience waits!
Below is a Stellarium script I adapted from the original zodiac.ssc that highlights the Zodiac constellations with art, names, and boundaries and it shows the ecliptic. The original script that comes with Stellarium had some features that I didn’t need so I copy-pasted a new one. My new script simply shows the Zodiac constellation art in just 5 seconds. This would take at least a minute to complete by hand! So, this is a great timesaver if you are presenting to a group via online zoom conference.
Stellarium Script – show Zodiac Art, Boundaries, Ecliptic
You can click here to download the script as a zip file. Unzip this download and you will have the .ssc file in your downloads area. Or you can just copy-paste the text below and create your own script file.
Here is a quick gif animation of what the presentation screen looks like while loading the Zodiac Art Boundaries and Ecliptic in the Stellarium Astronomy Zoom presentation.
Using the New Zodiac Art Boundaries and Ecliptic Script – Tutorial
Installing scripts is as easy as creating a text file with this script and placing the “script_name_here.ssc” file in the scripts directory. In this case, name your script file: zodiac_art_boundaries_ecliptic.ssc
After this “Zodiac Constellation Art Boundaries Ecliptic” script is installed in your Stellarium you’ll be able to get to it and run it from the Scripts tab of the Configuration window.
Instructions to Install a Stellarium Script
On Windows: You have to find the Stellarium User Data directory and inside that will be the scripts directory. (NOTE: I don’t have a windows machine so there is probably more information required here. Please add a comment to this post if you discover that I have left something out.)
If it doesn’t already exist, create a new folder named “scripts” – leave out the quotes.
Move your downloaded or created .ssc file to this folder.
On Mac: you have to control-click (hold the control button and click the mouse) the Stellarium.app in the Applications directory and choose “Show Package Contents”
You then navigate to the scripts directory in: Contents > Resources > scripts.
Place the script file in the scripts directory. Quit and re-open Stellarium and the script will be in the list of scripts in the Scripts tab of the Configuration window (see graphic above earlier in the article).
If you want to be fancy and use the included key command …
Using Stellarium Script Trigger “Sequence” commands
This custom Stellarium Script comes with a key command I programmed which is a “sequence command” – two steps. First do Control/Command-D, then release those keys and type the letter z key.
Try out the script and let me know what you think by typing in the comments field below! Also, if you want me to write a custom script to speed up your Stellarium presentations I’d love to help out – give me your suggestions.
Stellarium is a potent tool to help you see the sky
