We are all star dust

GreaterSkies builds a high-quality PNG image file, with the map of the sky as seen from a given place and time. And we print it for you. For example, the sky as it was when you met each other.

It is an original and very personal present, and a way to store for ever a memorable event.

A most personal present

Not all days are the same. Neither are their nights. Some you remember because something special happened. The sky as it was in that moment will be the best present. Seize the opportunity: Valentine's day, anniversaries, new born babies, weddings, company presents...

Prices and charity

We give 5% of what you pay to one of two worthwhile charities (you'll get to choose which one after payment.)
 

The science

All the stars up to magnitude 9 that were visible are plotted, with an approximation of their actual colors and with an area corresponding to their magnitude. This is usually around 15000 stars. Planets, moon and sun are also shown, as well as constellations and star names.

The computation of the positions and the generation of the map is done in Common Lisp. The positions should be accurate for dates between around 1900 and 2100.

 

Why

Because it is fun, pleasing, and it makes the prettiest present with a scientific bent. We are commited to helping you give personalized presents that are both a work of art and a treat for the curious mind.
