QHY 8Pro Cooled Color CCD Telescope Camera
The QHY 8PRO Color Cooled CCD Camera uses a Sony APS-C 6-megapixel sensor which is known for its low noise Performance. With its two-stage thermoelectric cooling, the noise will be further reduced by lowering the sensor's temperature to -45 degrees below ambient. With this technology, you to take exposures that are 30 minutes to an hour long!
Comparison of QHY8L and QHY8PRO
They QHY8L has a lower price point that the QHY8Pro. The major difference in the cameras is the way the sensor readout occurs. QHY8L uses a two-field readout where after an exposure is taken, the red pixels and half of the green pixels are read first, then the blue pixels and the other half of the green pixels then read.With Capturing fast objects, this can be troublesome due to the delay between the recording of each half of the image. The QHY8Pro doesn't have this problem since uses progressive scan to record each frame all at once. For long exposures, like in deep space imaging, there will not be a difference between the two-field readout or the progressive scan. For fast moving objects, the QHY8Pro will be the best choice.
