QHY 5-III Series USB 3.0 Guiding and Planetary Cameras

The QHY5-III series cameras are USB 3 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.

We offer the following products from the QHY 5-III series:

QHY5-III-462C

Lowest Readout Noise, Fast frame rates (120+ FPS)

QHY5III462C uses the latest (6th Generation) 2.1 megapixel IMX462 STARVIS CMOS sensor from Sony (available in color only). The pixel size is 2.9µm making it the same size and resolution as the sensor used in the QHY5III290 camera (product is dicontinued) that has been so successfully used for planetary imaging by some of the best planetary imagers in the world. The QHY462C has a fast USB 3.0 interface. 

The IMX462 sensor is back-illuminated and has new features that give it two significant advantages over other planetary cameras:

  1. the IMX462 sensor has sHGC for extremely low read noise (less than one electron) at high gain. This is ideal for stacking hundreds or thousands of short planetary images.
  2. it is exceptionally sensitive in the NIR. In this generation of sensor, the photodiode portion of the pixel well is deepened, allowing photons of longer wavelength to penetrate deeper into the substrate and thereby dramatically increases the sensor's sensitivity to red light and near infrared light (NIR). The RGB filters over the pixels become transparent at NIR wavelengths, so the sensor displays almost equal peak sensitivity to NIR light as it does to light in the visible spectrum.

The peak QE in the NIR around 800nm is as high or higher as the peak QE in the visible wavelengths. For planetary imagers using a methane filter that passes light around 880nm this is welcome news.

The QHY5III462C camera will include two 1.25" screw-in filters, a UV/IR cut filter to isolate the visible wavelengths for normal RGB imaging and an IR850 filter that will cut the visible wavelengths but pass wavelengths above 850nm. Together, this yields a camera that can image in (a) visible light only, or (b) NIR light only, or (c) combined visible and NIR. Passing all the light, visible and NIR, will produce a very sensitive luminance frame (when shot through a reflector or other scope capable of focusing visible and NiR together) for producing LRGB color images.

QHY5-III-174 Mono / Color
High QE 78% and USB 3.0 interface

The QHY 5-III-174 is the first in the QHY5III series CMOS USB 3.0 cameras. The camera is designed to be an excellent planetary, lunar, solar and meteor capture video camera. With a 50mm, F/1.4 C-mount lens it will record 8th to 9th magnitude stars at 30 frames per second (33 ms exposure). This high sensitivity with HD resolution will push video astronomy to new heights.

Sony introduced a global shutter (GS) CMOS imaging technology called PregiusTM that redefines the global shutter imaging category and provides the best of both worlds: fast frame rates and CCD-like imaging performance. The technology also offers reduced dark noise, which enables higher gains without compromising image quality, as well as higher quantum efficiency. The global shutter eliminates pixelization when imaging the moon and planets and moon caused by atmospheric agitation and high frame rates.

The unique QHYCCD design retains the 1.25-inch eyepiece design of the QHY5-II series but adds features for better cooling. This design is more efficient in transfer of heat to the outer case enabling lower noise especially in high ambient temperatures.

The 1.25 inch design also offers the shortest possible backfocus, making the camera ideal for off-axis guiding. In addition, the QHY5III174 uses a more robust LEMO style connector for the guide port. These connectors are known for being both rugged and reliable.

The QHY5III174 is available in both mono and color versions. The camera is well suited for solar imaging using short focal length telescopes that will capture a full solar disk within the FOV.

QHY5-III- 178 Mono / Color
Back-Illuminated, 6,0 Megapixel

The QHY 5-III-178's sensor is Sony's STARVIS BSI image sensor. STARVIS is a trademark of Sony Corporation. BSI means the sensor is Back Side Illuminated which dramatically increases the sensor's sensitivity and produces high picture quality in the visible-light and near infrared light regions. Available in both color and monochrome.

This sensor has small 2.4um pixels and a 1/1.8-inch sensor that can be used for high-precison guiding data with a good FOV for easily finding guide stars. The camera is designed to be a wide FOV autoguider, high-resolution planetary camera, and entery level deep sky camera. For deep sky imaging, the QHY5III178 uses our proprietary anti-amp glow control function that reduces amplifer glow significantly Output is 50 FPS at full resolution and up to 190 FPS at selected ROI. The cooled models with this sensor are the QHY178M/C.

QHY5-III-185C
1/1.9 inch, Color Camera

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.

QHY5-III-290 M
Back-Illuminated, Best Planetary Imager

QHY5III290M/C uses the SONY IMX290 STARVIS Exmor R back-illuminated CMOS sensor. STARVIS means you can see very dim stars in real time video. The QHY5III290 can capture magnitude 9 stars with a 50mm F/1.4 C-mount lens.  Compared to the IMX236 sensor, for example, the IMX290 has twice sensitivity for visible light and three or more times the sensitivity in near infrared.  The QHY5III290 also has ultra low read noise.  The back-illumination and low read noise make this camera an ideal video astronomy camera.

The small 2.9um pixel size is also ideal for planetary imaging.  The QHY5III290 has a fast USB 3.0 interface and produces 135FPS at full HD output . The camera has 10/12-bit ADC and it outputs an 8-bit or 12-bit image.The QHY5III290M can be regarded as the next generation in monochrome planetary cameras after the QHYCCD QHY5L-II-M. The cooled model with this sensor is the QHY290M.
