My modification to the 450d has really helped bring out the colour of this Emission Nebula.  If you are interested in modding your own Canon Xs or XSi, you can find the tutorial from Gary Honis below. The photo above was taken on the night of October 25th under clear skies in Wellandport, Ontario. I feel like I want to shoot every deep-sky object over again now that my camera records so much more red nebulosity!  I am excited to image some of the Winter objects that will be spending some time in our night sky over the next 2 months!

NGC 1499, or "The California Nebula" is a large emission nebula located in the constellation of Perseus.  It's shape resembles the outline of the State of California.  The California Nebula is very difficult to observe visually because of it's low surface brightness, but shows up well in long exposure photography.  It was discovered by E.E. Barnard in 1884.

Canon 450D / 1000D - Gary Honis Full Spectrum Mod


Gary Honis will take you step by step of how to remove the IR cut filter in your Canon XS or XSi in the video below. Removing this filter from the camera allows H-Alpha wavelengths to pass through for deep-sky imaging. I was able to modify my DSLR myself by watching this video. I performed the "full-spectrum" mod, and did not install any additional new filters to the camera. I only removed the IR-Cut filter. My clip-in Hutech IDAS LPS filter protects the sensor.
