Overview
The ToupTek ATR432M is a cooled mono astronomy camera with Sony’s IMX432: 1.8 megapixels of very large 9 µm pixels, a 1.1″ format and a global shutter.
It suits solar imaging in hydrogen-alpha and calcium, and the Moon. The global shutter reads the whole frame at once, at up to 109 frames per second, with no rolling-shutter distortion. Big pixels also match long focal lengths; on a 2000 mm SCT it samples at about 0.93″ per pixel. Full well is 100 ke⁻. Use high gain mode for faint targets, where read noise falls to 2.4 e⁻.
Cooling, dew and power
Two-stage cooling takes the sensor up to 42 °C below the air temperature. It holds the set point to within 0.1 °C, so dark frames can be reused from night to night. A heater on the front window has four power settings and can be switched off in software. Cooling needs 12 V; the 12 V 3 A power supply is in the box.
Back focus and connections
Back focus is 17.5 mm from the M42 thread. Adapter rings and extension tubes are included to build out to the spacing your flattener or reducer needs, usually 55 mm. A 512 MB buffer holds each frame while it transfers, so a slow USB link doesn’t drop frames.
