ToupTek ATR432C Cooled Colour DSO and Solar Camera

Long focal length telescopes produce very high magnification and can image targets that are smaller than other telescopes can get. However, the long focal length results in a high focal ratio, meaning the image can be very dim. To compensate for this, you need large pixels. The ToupTek ATR432C is made up of 1600 x 1100 huge 9 μm pixels. This gives the sensor a 1.1-inch (14.4 x 9.9mm) optical format. So, for example, with a Celestron 925 SCT, the galaxy NGC 1365 will fill the sensor and be sensitive enough to get an excellent image.  Additionally, the camera has a TEC cooling system which maintains precise temperature control within a deviation of 0.1℃, while the dew prevention heater (window heating) further enhances performance. This will keep the sensor from being getting warm over a long exposure and being affected by noise. The camera is also perfectly suited for solar and lunar imaging with shorter length telescopes. Paired with a telescope of 1000mm focal length or less, the entire solar or lunar disk can fit on the sensor. It offers support for high frame rate mode (109FPS at all Pixel Readout 12 bit) and has a readout noise level as low as 2.4e.   DDR3 The ToupTek ATR432C camera has a 512MB ultra-fast memory buffer to ensure stable image transmission. Two stage TEC cooling system ATR432C is designed with an integrated heat dissipation structure and an efficient cooling module. The cooling system of ATR432C features a two-stage Thermoelectric Cooling (TEC) with controllable electric fan assisting in heat dissipation. This allows the image sensor to operate at temperatures up to 42 degrees Celsius lower than the ambient temperature. The exposure time can be set for up to 1 hour, ensuring that every minute detail is captured. Even in summer, it can still run stably all night with cooling temperatures ranging from of -5°C to -10°C. Anti-dew technology ATR432C adopts the new anti-dew technology, which can effectively solve the condensation problem through heating. This heating function consumes about 5 watts, which can be turned off via software to save power. Additionally, the dew heater at the protection window has 4 adjustable levels, allowing users to find the heating power that best suits their needs.
