Cooled DSLR Project

Here’s my recent version of a peltier-cooled Canon 450D for astro-imaging. It is housed in an aluminum case with custom-fabricated 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. During operation, sensor temperature drops to 35 degrees C below ambient.

    1. I assume you meant entry level DSLR that may be used for astrophotography as well? I really cannot specify any particular brand or model. Essentially, any camera with manual settings is good enough as an entry-level camera. Basically any DSLR that suits your budget:)
