QHY Astrophotography

The QHY5L-II Series uncooled cameras fit in a standard 1.25-inch eyepiece holder and have an adjustable location ring for confocality with an eyepiece. They are ideal for use as low-weight autoguiders or planetary cameras where short exposures are typical. Description The cameras come in very small but powerful packages! The improved thermal design allows the heat generated by the CMOS sensor to be transferred externally to the telescope’s eyepiece tube. QHY5L-II is one of our most popular guide cameras, it has high sensitivity, an exceptional 74% QE, and low noise. The read noise is remarkably low (~ 4 electrons) and...

The main purpose of the OAG is to use the same optical path as the main camera. This avoids the problem of differential deflection that can occur when using a separate optical system for guiding. This method provides more accurate guiding and sharper images. Description QHYOAG has three models. The major difference is its different diameter. The three model are QHYOAG-S,QHYOAG-M,QHYOAG-L. QHYOAG is a thin and solid design. The OAG main body is just 10mm thick. Adding an M42 thread or M54 adapter ring adds only 3mm for a total thickness of 13mm. There are six 3mm through holes in...

The new CFW3 series filter wheels are available in four sizes to accommodate filters from 1.25-inch to 50 millimeters square. The small and medium sizes are also available in SR/US variants, which accomodate different filter thinknesses. Description For filter wheel control a custom QHY 4-pin filter wheel port is included that provides power and control signals for QHY dual control filter wheels like the series 3 filter wheels. Both the series 2 and new series 3 filter wheels can be controlled by either an independent external program using the filter wheel’s USB port or via the QHY 4-pin serial port....

The QHY5III462C camera uses the latest (Sixth Generation) Sony 2.1 megapixel IMX462 STARVIS CMOS sensor. The pixel size is 2.9u making it the same size and resolution as the sensor used in the QHY5III290 camera that has been so successfully used for planetary imaging by some of the best planetary imagers in the world. Like other cameras in the 5III series, the QHY5III462C is USB 3.0 powered and controlled. No additional power is required. Description The IMX462 sensor is back-illuminated and incorporates new technology that gives it some significant advantage over other planetary cameras: First, the IMX462 sensor has sHCG...

QHY5III200M is a new generation of QHY5III V2 series planetary guide camera, using domestic CMOS, with excellent quality, and near-infrared high sensitivity similar to 5III462C. QHY5III200 is also the first mono CMOS planetary camera with near-infrared enhancement characteristics QHY developed. In addition, the 4μm large picture elements make it easier to use for guiding. The product comes with filters including the IR850 filter. Features 512mb DDR3 The QHY5III (Ver. 2) series planetary and guiding cameras are all equipped with a 512MB DDR3 image buffer which can effectively reduce the pressure on computer transmission, a great help for planetary photography which...

The QHY5-III series cameras are USB3 super-speed cameras and guiders. They can be used in a standard 1.25-inch eyepiece holder. All QHY5III series cameras come in a very small but powerful package! Description QHY5III290M uses the IMX290 STARVIS Exmor R back-illuminated CMOS sensor. Available in monochrome version. Extremely low read noise. 1920×1080 full-HD resolution. 1/2.8-inch sensor size. This might be the highest-sensitivity sensor from Sony with such a small pixel size. Specifications CMOS Sensor Sony IMX290 Color/Mono Mono FSI/BSI BSI Pixel Size 2.9um Pixel Array 1920*1080 Effective Pixels 2MP Sensor Size 1/2.8 inch Frame Rate @Full Frame 135FPS Frame rate...

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). Output is 50 FPS at full resolution and up to 190 FPS at selected ROI. Specifications CMOS Sensor Sony IMX178 Color/Mono Mono FSI/BSI BSI Pixel Size 2.4um Pixel Array 3072*2048 Effective...

QHY5III485C uses Sony’s new IMX485, back-illuminated, 8.4 megapixel color CMOS sensor with an array of 3864 x 2180 pixels at 2.9um. With USB 3.0 interface, the full frame rate of 44 FPS at 8-bits or 18.5 FPS at 16-bits. Smaller regions of interest will yield even faster frame rates. Description The resolution of QHY5III485C is 16:9, which is equivalent to the mainstream video output ratio. With the native high resolution, 485C can play a special role in recording astronomical video and astronomical science live broadcast. QHY5III485C is specially equipped with 128MB DDR bulid-in image buffer. In non-video output mode, DDR...

The QHY5-III series cameras are USB3 super-speed cameras and guiders. They can be used in a standard 1.25-inch eyepiece holder. All QHY5III series cameras come in a very small but powerful package! Description QHY5III174M/C uses a 1/1.2-inch, 2.3 Megapixel, SONY Exmore IMX174 CMOS 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 makes it excellent for deep-sky imaging as well. Typical of all models in the QHY5III Series, this camera produces a high frame rate with the USB 3.0 interface,...
