Choose a place and a time, and get A high-resolution PDF poster with a beautiful rendition of the stars and planets as they were over that special place, on that special moment.
The perfect gift for anniversaries —the night you fell in love, the day you got married.
Great as a newborn's keepsake present, showing the first sky over the child.
"The product quality meets my expectation and makes a very special anniversary gift."
"Just wanted to say that amazingly we got the print yesterday on my husband's birthday! He loved it of course. Thank you so much for such a speedy turnaround—will definitely recommend you to friends."What our customers are saying
Make it even more memorable.
We'll create high-quality PDF image files with the map of the sky as seen from a given place and time. For example, the sky as it was when you met each other. The sky as it was when your daughter was born.
It is an original and very personal present, and a way to store for ever a memorable event. Seize the opportunity: Valentine's day, anniversaries, new born babies, weddings, company presents...
Not all days are the same. Neither are their nights. Some are worth remembering because something special happened. The sky as it was in that moment will be the best reminder.
"Gorgeous and so perfect for a gift! THANK YOU for your great customer service as well! Highly recommend buying from Greater Skies!"What our customers are saying
You get three high-definition image files, each optimized to be printed at a different size: from large poster to letter:
A file optimized for printing at 20x27in (50x70 cm),
one optimized for printing at 16x20in (40x50 cm),
and one optimized for printing letter-size.
We'll compute your charts for you as soon as you order them, and you'll be able to download them within seconds.
If you want, we'll also print the chart at 20x27in with photo quality and send it to you.
"What a great idea! Print is really neat and special to us on our wedding day. Arrived very quickly, with awesome service and attention to detail. Much appreciated."What our customers are saying
You get to chose the place from which the sky is seen, and the date and time. You can also add a caption, something like The sky as it was seen from Barcelona on that special day (don't worry: we'll generate it for you if you don't want to personalize it). And you can write a personal message, that will be shown below the caption.
No it is not. Really. Do take a look at the samples, explore and zoom in. The programs to produce star charts are not even close to this level of detail. They cannot produce high-quality posters. Also, Greaterskies posters are beautiful.
All the stars up to magnitude 7 that were visible are plotted, with an approximation of their actual colors and with an area corresponding to their magnitude. This is usually between 7000 and 8000 stars. Planets, moon and sun are also shown, as well as constellations and star names.
I wrote the program that computes the positions of stars and planets, and that generates the map, in Common Lisp —a programming language invented back in 1958 and that I rather enjoy using—, and the celestial coordinates come from the HYG database. Over the last years I have worked in optimizing the renderization of the map, striving to make it both accurate and beautiful.
For this is not a normal star chart, intended just to show where major stars are located: every tiny dot in your map corresponds to a star that was actually there. The positions are accurate for dates between around 1900 and 2100; we still haven't implemented the extra computation to produce accurate star charts beyond these dates.
