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.
