Clearskypix is a website and a blog about astrophotography.

My name is Francois; I've been an amateur astronomer since 1988.

In 2004, I purchased my first astrophotography equipment and in 2008, I built my own observatory. Since then, I cannot count the number of hours I have spent building, learning and trying. It truly as been a humbling experience that I want to share through these pages and I sincerely hope it will continue for a lifetime.
