Welcome to my home page, I hope you will enjoy the photographs.
My name is Eddie de la Cruz and I am a keen photographer with special interest in macro and astrophotography. As for astrophotography my home is located in the western suburbs in Sydney Australia where light pollution is very dominant making it very difficult to capture images using the simple RGB setup to capture real colors of nebulas and galaxies. After some months of trying various light pollution filters with little success, I decided to switch to narrowband filters with substantial improvements, overcoming light pollution and being able to capture much more details. Narrowband does not produce real colors because the narrowband filters only allows limited light waves to pass through (blocking most of the light pollution waves which makes the image very noisy/grainy). The most commonly used narrowband filters are Sii (sulfur 2 (671.6nm and 673.1nm)), Ha (hydrogen alpha (653nm)), and Oiii (oxygen 3 (495.9nm and 500.7nm)), and the most commonly used processing is based on the Hubble Palette which is Red=Sii, Green=Ha, and Blue=Oiii. This means when viewing images processed with the Hubble Palette, reds represents sulfur 2 (Sii), greens represents hydrogen (Ha), and blues represents oxygen 3 (Oiii) – yellow is a combination of Sii and Ha. Although narrowband does not represent real colors, I feel it gives you a much more spectacular image, I hope you feel the same.
