Full Frame Sony IMX455 Sensor
As mentioned above, the onboard Sony IMX455 is the heart of this QHY600PH-M-SBFL camera, providing a pixel array of 9576 x 6388. That’s 61.17 MP of resolution! Enjoy capturing large, intricate scenes with the full frame format, and enjoy beautiful detail with the 3.76um x 3.76um pixels. The minimal 1.0e- to 3.7e- read out noise, 16-bit ADC, and impressive >51ke- full well capacity deliver remarkable resolution on nebulosity and galactic structures. Region of interest (ROI) is supported with this QHYCCD camera, helping you maximize your frame rate and dial-in on the desired details.

Hardware Highlights
As opposed to front illuminated sensors, the necessary wires and transistors of this sensor are fitted behind the pixel wells, offering elevated photon collection for a higher signal to noise ratio. This careful circuitry is continued with the placement and construction of the camera’s amplifiers. As such, you can expect zero amp glow within your frames! The dual stage TEC cooler offers two approaches for your convenience: -35℃ below ambient for long exposures, and -30℃ below ambient for high frame-rate, short exposures. On the optic window itself, a built-in dew heater protects from internal humidity condensation for the utmost clarity. Another key benefit is the addition of a 2GB DDR3 memory buffer. This addition ensures smooth data transfer and helps prevent dropped frames.

Software Highlights
While too high of voltage can absolutely be detrimental to the internal circuitry, too low of voltage can be as well. The integrated UVLO (Under Voltage Locking) protection helps prevent this, with the all-in-one driver and SDK (after 2021.10.23 version) providing a warning when the input voltage of the camera is below 11V. Built into the camera itself, TRUE RAW IMAGE OUTPUT delivers your frames with the original signal only. This means you won’t have to worry about internal software pre-processing your images, ensuring every bit of detail is collected. Oftentimes back-illuminated CMOS cameras can be subject to a change in thermal noise over time. To combat this, QHYCCD uses innovative internal suppression technology to significantly reduce the effects of this noise for cleaner, crisper images!

Power and Ports
On the body of this QHY600PH-M-SBFL camera, you’ll find a number of ports: a 12V threaded power port, a USB3.0 Type B port, and a 4-pin CFW interface. With the threaded housing of the power port, faulty power connections are a thing of the past. This interface ensures a solid power connection all night long. The employment USB 3.0 enables smooth, seamless data transmission, with the opportunity for enhanced data as well. By adjusting the USB traffic to Single Frame mode within your downloaded software, horizontal banding can be effectively reduced within the final stacked image! When adjoining the included QHYCCD CFW3L, simply connect this filter wheel to the CFW port for efficient, streamlined connection. Included within the box is a 12V power adapter and AV power cable, as well as a USB cable for use straight out of the box.

Multiple Readout Modes
Multiple readout modes are available for this QHY600PH-M-SBFL camera: Photographic DSO, High Gain, Extended Fullwell, and Mode-2CMS for each of the previously listed modes. Photographic DSO mode is ideal for most deep sky imaging applications, and it’s recommended to set configuration as your default gain setting. High Gain Mode is great for capturing very dark objects, such as dusty, diffuse nebulae where details are very dim and hard to resolve on their own. With the Extended Fullwell Capacity mode enabled, this QHYCCD camera can achieve an extremely large full-well charge value of nearly 80ke-. This expanded capacity enables greater dynamic range and larger variations in magnitude of brightness, making it wonderful for imaging both bright and dim objects within a singular field of view. The Mode-2CMS applied to any of these three basic settings can greatly reduce readout noise (by secondary sampling) while keeping the same full well value and system gain! Thanks to the innovation from QHY, you’re well equipped in maximizing the potential of every imaging session.

Your Backfocus Needs Covered
QHYCCD includes numerous adapters and spacers within this package: (1) 5mm M54-M48 threaded output adapter, (1) 5mm M54-M54 threaded output adapter, (1) 4mm spacer, (2) 3mm spacers, (1) 1mm spacer, and (1) 10mm spacer. With so many options to choose from, achieving the industry standard of 55 mm of backfocus is a breeze. For example, if you’re connecting your QHY600PH-M-SBFL to the included CFW3L and a user-supplied QHY OAGM-Pro, the 5 mm M54 or M48 output adapter will be needed to reach 55 mm of backfocus (the backfocus consumed by this SBFL version camera equals 12.5mm when connected to a QHY filter wheel). Take a look at this diagram for an example of common setups with this QHY600PH-M-SBFL camera.

Short Backfocal Length Version
This QHY600PH camera is a SBFL (short back-focal length version). This means it’s specially suited for users of DSLR lenses which require short backfocal lengths. For reference, the front portion of this SBFL camera is fitted with a 14.5 mm back focal distance, in contrast to the standard 17.5 mm back focal distance of other cooled astroimaging cameras. Please note: when used with the included QHYCCD filter wheel the backfocus consumed by this SBFL version is 12.5 mm, not 14.5 mm.

Included QHY 3rd Generation Filter Wheel
With seven filter positions at hand for 50 mm round filters, this large “L”, version of the QHYCFW3L is ideal for housing two of the most common filter sets for monochrome imagers: LRGB and SHO narrowband. Effortlessly swap between sets for various imaging applications. This filter wheel is compatible with up to 10 mm thick mounted filters (excluding the filter thread height) and unmounted filters of varying thicknesses. As a third-generation QHY filter wheel, the ultra-thin hybrid stepper motor and friction drive deliver zero backlash, making this a highly useful tool for precision-oriented astrophotographers! A single piece of CNC-machined aluminum makes up the body for a sleek, polished finish, noting 21.5 mm of backfocus is consumed by this QHYCFW3L.

Updated Body Design!
The QHY600M now comes with an elevated heating board. QHY has raised the board by 5mm. This decreases the likelihood of fogging, but does not change Back focus length calculations or any other function. While the above images currently show the regressed heating board, to the left is a visual aid to show this update. The picture shows the QHY268 Monochrome camera but is still a good illustration of the change. Please Note: This change is still being rolled out by the manufacturer, so we cannot guarantee which version of the body design you will receive. If you have any questions or concerns, please don't hesitate to call us at 1-800-266-9590 or send an email, and we will be happy to help you. Thank you!
