@about me
Very cool photo of me on Jökulsárlón beach (Iceland), by my friend Juanlu

MSc in Computer Engineering and MSc in Data Science. Full-time husband and father. By day, an IT Engineer for the Government of Andalucía, Spain. By night, an astronomer and astrophotographer, whenever possible.

I developed passion for astronomy since I watched Carl Sagan's Cosmos series as a kid. The astrophotographs of David Malin and Akira Fujii also captivated my imagination. I read every astronomy book that crossed my path, but didn't really experience the wonders of visual, naked-eye observation until my early adolescence when for the first time I could be under relatively dark skies, at least dark enough for a city boy. On my twenties I had access to a 8" telescope and began to use it at the rooftop of my home, downtown Seville city, in Spain.

After borrowing my father's old film camera for a few times, finally in 2002 I purchased my first digital camera for daytime photos and naturally I started to photograph some night landscapes and telescopic targets. That was the beginning of a long journey with many trips and interruptions, but eventually I managed to made my path. I'm a self-taught photographer, which means that almost all I learned, and still learn, came from others, some renowned, some anonymous, all more skillful than I am, so thank you sincerely.

Digital format enabled me to explore photography without the stress of wasting film. Naturally I evolved also in daytime photography, which I also love, as an expression for the delight of nature, architecture, and of course, people. I like to travel, usually with my loved family, and bring the camera with me wherever I go.

As an enthusiast on technology, I chose to study Electronics in secondary school and then made a career on Computer Engineering. I enjoy making photographic accessories by 3D-printing custom models and developing the electronics for them. In 2019 I reinvented myself as a data scientist, something that naturally influenced my perspective about astrophotography.

I'm a member of the Astronomía Sevilla Association, the Andalusian Network of Astronomy (Red Andaluza de Astronomía, RAdA), the Federation of Astronomical Associations of Spain (Federación de Asociaciones Astronómicas de España, FAAE) and the Association against Light Pollution Cel Fosc.

Within FAAE, I'm a member of the Astronomical Computation Group (GCA, Grupo de Cálculo Astronómico), which is responsible for the publication of the Journal of Computational Astronomy and Astronomical Computation (JCAAC).

Since 2024 I'm also a Divulgador FAAE (certified astronomy outreach educator).

In this site I wanted to share with you some of my photographic work, hoping that it evokes you the same emotions that I experienced when I was there, releasing the shutter.
