Welcome to my world of astrophotography. I am the developer of Astrodon filters for astrophotography and research, But, first and foremost, I am an astrophotographer. I view myself as a technical artist. A landscape photographer on a cosmic scale. This site shares my passion for this demanding, technical hobby with images of sometimes famous and often times rarely photographed galaxies, nebula and star clusters. It is a humbling experience to present to you a galaxy in vivid colors, whose light that we see left that galaxy when dinosaurs roamed our planet. Is it still there? Are they looking toward our galaxy with the same degree of wonder? I invite you to explore this world with me.
