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.

Sky-Watcher Equinox 100 ED

The Sky-Watcher Equinox 100 ED serves as my main telescope, both for visual use and for astrophotography. The telescope comes with a wooden aluminum-lined carrying case. It is supplied with two eyepieces: 25 mm (left) and 5 mm (right). At f=900 mm, the 25 mm and the 5 mm provide magnifications of 36x and 180x, respectively. Supplied also is a 90-degree 2-inch diagonal mirror. The telescope comes with an 8 x 50 finder scope.

The Optical Tube Assembly (OTA) features a 4-in f/9 extra-low dispersion (ED) apochromatic (APO) lens design, which makes it highly suitable not only for visual observation but also for astrophotography. It features a 2-inch/1-inch dual-speed Crayford focuser with a thumbscrew underneath for locking the draw tube once focus is achieved.
