The idea of GreaterSkies was forged in 2005. I am an R&D engineer specialized in printing and I thought it’d be nice to take advantage of the huge and good printers around me to print a really good star chart. Good as in thousands of stars, with colors, in their right position, as seen from a given vantage point at a given time. And big, really big
It is the curse of the engineer: if it can be done, it will be done. I learnt how to compute the position of stars and planets, I found out about the HYG database (which is basically a catalog of stars), and I learnt how to render those stars beautifully in two dimensions (paper!). Then I put together a program that produced a nice file with thousands of stars and all the planets, with constellations and grids (it helped when they demoted Pluto from its planet status, as it was the hardest to compute for). I made the program so that it would draw pictures of the planets instead of their symbols, a feature loved by my non-astronomer friends.
It was an interesting project, and successful in a way: I made several charts as birthday presents, and gave a specially big one to the Fabra observatory here in Barcelona, where it went on display. After that, I left that program somewhere in my hard disk, and forgot about it.
