I share a short story and a little piece of work. Both of them are born out of several encounters.
The lockdowns of 2020 made me bring my (old) telescope out of the attic.
Then came the 1st encounter with a shy 10-year-old neighbour. He had his mum ask me if he could come and look through the telescope because he was fascinated by the sky but had never looked into an instrument.
The 2nd was simply work-related and unconnected to astronomy: I had to write tutorials and I wanted to brainstorm beforehand in order to collaborate effectively with a young filmmaker.
So I found an opportunity to realise a decade old ambition: to record a full rotation of a planet (with what I had on hand ).
As a challenge I tried to achieve the whole thing with open-source software.
Several outstanding videos of spinning planets are available online.
As far as I know, these animations are created by mapping a “world map” of the planet on a computer globe (a homemade “blue marble”). The world map is made of a few high-res pictures stitched together to cover all the planet time zones. Then a software creates an animation.
For my part, I wanted to make a "real" time-lapse of a whole rotation just for the sake of it.
Hopefully, Mars was in opposition...
It all started with a handful of images acquired at 15-minute intervals to show the real-time rotation of the planet to a little boy in awe...
Of course, there’s no high-resolution ambition.
- Here's a A Martian ballade...
I also have a new animation in mind for which I will ask some questions later.
