QHY 178 Cooled Color CMOS Telescope Camera
The 178 Cooled CMOS Camera- Color by QHY:
The QHY 178 can boast a whopping 3072x2048 resolution, placing it up there with the real CMOS contenders. What is more, it has an incredibly small pixel size at only 2.4 um and a large FOV that makes it ideal for use as a guide camera. It excels as a Guide Camera, it's wide FOV and high resolution making it more than capable of locating a high number of guide stars. It is also a top notch planetary imaging camera, and even has applications as an entry level deep sky imaging unit! For deep sky imaging, this camera has the anti-amp glow control function which can reduce the amplifier glow significantly.
The sensor used in the QHY 178 is Sony's trademarked new StarVis BSI image sensor. The STARVIS is back-illuminated pixel technology used in CMOS image sensors for high sensitivity applications. With a sensitivity of 2000 mV or more per 1 um-squared, its quality is truly stellar in magnitude. It is fully capable of realizing high picture quality in the visible-light and near infrared light regions, and is all in all a splendid sensor to use. But it's not just about that sensor, heart of any camera that a sensor is- there's a lot more to appreciate here, despite how much saying that promises in this case!
To get a bit more in depth, lets start with a closer look at one of the core facets of this marvelous imaging device: the two stage Thermo-Electric cooling system that keeps the cameras internal temperature regulated smoothly and cleanly, reducing dark noise interference and all around improving your imaging experience. This powerful cooling system is capable of attaining a cooling delta of -40 degrees celsius lower than the average temperature of the cameras environment. This is of particular value on a warm summer night, where higher temperatures could cause dewing or other sources of internal interference in the cameras mechanisms. In general the lower temperatures attainable through high power cooling are a great boon to quality imaging. Speaking of dewing, this camera has another potent countermeasure to prevent that from even being a possibility worth considering, in the form of a fully vacuum sealed sensor chamber combined with both a silicon gel tube socket and a window heater that all combine to keep everything perfectly dry within that chamber.
Moving on to another exemplary trait of this splendid camera, lets talk about the inbuilt 128MB DDRII image buffer that is another excellent component of this camera. This buffer exists to safeguard you from unexpected drops in transmission, and to ensure that every pixel that you've captured after a long night of imaging can be safely transferred to your computer for processing without data loss in transit. This frame buffer accomplishes this all by storing image data in the camera itself until they can be safely transmitted. This can also help your data run more smoothly on slower computers when linked to them.
In summary this camera is designed to clear away as many obstacles as possible between you, and capturing the most beautiful full color images of the starry night skies possible. We're comfortable saying that its likely to do a good job of it to boot, with the heavy duty cooling and numerous other high quality features of this camera combining to make your hobby as easy as it could be. And due to it being of a CMOS format rather than CCD, all this top notch quality and advanced technology is being offered at a supremely affordable price!
