  • Reduced amp-glow for superior imaging of faint objects

Product Details

1. Cooled Astronomy Camera for Solar System and Deep-Sky Imaging

The QHY178M is a cooled USB 3.0 monochrome astronomy camera that’s ideal for planetary and deep sky imaging. The 178M uses the back-illuminated 1/1.8” Sony STARVIS Exmor-R IMX178 CMOS sensor with small 2.4um pixels in a 6-megapixel array. The sensor sits in a sealed and heated chamber to prevent dew from forming on the sensor or window. This ColdMOS, or cooled CMOS sensor has a resolution of 3072 x 2048, and has a data transfer rate of 50fps at full resolution. The read-out nose of the camera is 2.4e at low gain and 0.9e at high gain. 

2. Two-Stage Cooling for Low Noise and Sealed Chamber to Keep Sensor Dry

The QHY178M monochrome camera comes with a two-stage TEC cooling and temperature control that cools the camera as low as -45C below ambient, which is ideal for warm and damp summer observing conditions. QHY has also built in anti-dew technology into the QHY178. The sensor chamber is sealed and incorporates a silicon gel tube socket and heater to help keep both the sensor and the sensor window dry.

The cooler requires +12VDC input (power supply not included).

3. Built-In Buffer for Reliable Data Transfer

The QHY178M has a built-in 128MB DDRII image buffer. The benefit of the image buffer is that the memory will cache the image and transfer it to the computer when the USB interface is not busy or being interrupted, and the frame will not be lost or corrupted.  This buffer also allows a slower computer with USB 2.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals.  This buffer also makes it possible to run multiple cameras on the same computer without USB transfer problems. 

4. Reduced Amp-Glow for Superior Deep-Sky Imaging

The QHY178M camera has a control circuit to reduce amplifier glow significantly, especially important for longer exposures of deep-sky objects. Camera ports include a 6-pin RJ11 Guide Port and a 4-pin CFW2 Filter Wheel Control Port, allowing you to add an optional autoguider or filter wheel to give you more options and control over your astro-imaging.
