The QHY5-III series cameras are USB3 super-speed cameras and guiders.  They can be used in a standard 1.25-inch eyepiece holder and have an adjustable location ring for confocality with an eyepiece.  All QHY5III series cameras come in a very small but powerful package!

QHY5III174M/C uses the 2.3 Megapixel IMX174, 1/1.2-inch Exmor sensor with global shutter. Available in both monochrome and color.  The large sensor size is a great choice for solar imaging, and the large pixel size and high QE (78%) makes it excellent for deep-sky imaging as well.

QHY5III178M/C uses the new 6.0 Megapixel IMX178 STARVIS Exmor R back-illuminated CMOS sensor. Available in both color and monochrome. With its small 2.4um pixels and 1/1.8-inch sensor size, the monochrome QHY5III178M is a superb guiding camera due to its advantages in resolution and wide FOV, plus its extraordinary sensitivity due to the STARVIS Exmore sensor.  (STARVIS is Sony's designation for sensors that can record real time video in starlight).

QHY5III185C is a 1/1.9inch format, 1920 x 1200, USB 3.0, Color CMOS Camera with ultra-high sensitivity and very low read noise.  The pixel size is 3.75um x 3.75um.  Maxium Frame rate is 100FPS @ full resolution.  The CMOS sensor is a SONY IMX185 noted for its very good SNR1 score

QHY5III224C uses the IMX224 sensor (available in color only). With its extremely-low readout noise of less than one electron, the IMX224 sensor achieved the top score in the new SNR1 index proposed by Sony for picture quality at low illumination. It is one of your best choices for color planetary imaging.

QHY5III290M/C uses the IMX290 STARVIS Exmor R back-illuminated CMOS sensor. Available in both color and monochrome versions. Extremely low read noise. 1920x1080 full-HD resolution. 1/2.8-inch sensor size. This might be the highest-sensitivity sensor from Sony with such a small pixel size. The QHY5III290M can be regarded as the next generation in monochrome planetary cameras after the QHYCCD QHY5L-II-M.

For TE cooled versions of cameras using these sensors, please see our Small Cooled CMOS Cameras.
