Overview
The ToupTek ATR183M is a cooled mono astronomy camera with Sony’s IMX183, a 1″ sensor of 20 megapixels with small 2.4 µm pixels.
It suits narrowband and LRGB at short focal lengths: at 400 mm it samples at about 1.24″ per pixel, giving fine detail from a small refractor. 1.25″ filters cover the 15.9 mm diagonal at most focal ratios, keeping filter costs down. Full well is 15 ke⁻, so bright stars saturate sooner and shorter sub-exposures help. The IMX183 shows some amp glow, which dark frames remove.
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.
