Canon 1100D Modification

The Canon 1100D modification involves the removal of the stock UV-IR filter, making the camera more sensitive to H-alpha wavelengths emitted by most deep-space nebula.

Celestron Travel Scope 70

The Celestron Travel Scope 70 is a small telescope designed for viewing distant land-based targets (such as birds and trees) and for casual astronomical observations. While many enthusiasts would purchase this telescope as a grab-and-go telescope, I intend to use it as a guide scope for my autoguider setup.

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.
