Modified Canon 450D DSLR (March 2014)

My most recent project: a camera that can take photos of deep space! It has special filters to make it more sensitive to galaxies and nebula, and operates at freezing temperatures to minimize sensor noise.

Shown in above is my most recent version of a TEC-cooled (Peltier) Canon 450D DSLR intended for astro-imaging. This one has been housed in rigid plastic case with custom-fabricated aluminum lens mount to accept standard Canon lenses and T-adapters. The camera’s stock filters (both the IR and the dust-cleaning filter) were replaced with a Baader UV-IR filter to optimize sensitivity to H-alpha wavelengths and also serve as the sealed chamber’s optical window. During operation, sensor temperature drops to 35 degrees C below ambient.
