Product Description

ASI294MM-P is a back-illuminated, 4/3” format, 14-bit ADC camera with 4.63um pixels *(. It is the mono version of ASI294MC Pro, one of the top selling cameras from ZWO. It has an impressive 66ke- full well capacity and 4144*2822 big resolution.

Not only does it have a very high QE value with a peak at about 90%, but feature an ultra-low readout noise of 1.2e. If you are seeking for a small-format mono camera for astrophotography, then ASI294MM-P gonna be your ideal choice.

14-bit ADC and 13stops dynamic range

ASI294MM Pro has very similar parameters as its color version. Both have the 14bit ADC and a high dynamic range of 13 stops, which is even higher than that of ASI1600MM Pro camera.

Unlocked Bin1 Mode

Yet another perk of the ASI294MM Pro is that the pixel size is switchable – the default setting is Bin2, but you can switch to Bin1 anytime in your astrophotography software. This changes the pixel size into 2.3um and increases resolution to 8288×5644. This is what we called “Unlocked Bin1 Mode”. The ability to unlock bin1-mode was a popular request from our customers. Of course we listened to you and worked quickly to make it possible.

Remember that using Bin1-mode will decrease the full well capacity compared to the standard bin2-mode.

Unlocked Bin1: 12bit ADC, 2.3um pixel size, 47 megapixels, 8288*5644 resolution, 14k full well capacity.
Bin2: 14bit ADC, 4.6um pixel size, 11.7 megapixels, 4144*2822 resolution, 66k full well capacity.

Backlit Sensor

The back-illuminated CMOS sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.

With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate.

Camera Performance

Large well depth capacity, low read-out noise and high dynamic range.

The full well capacity of 66387e of ASI294MM Pro is near the top of all ASI DSO cameras. It ensures a very high dynamic range up to 13stops that will greatly reduce overexposure probability and help gain richer color gradation.

When the gain value is 120, the magical HCG high gain mode is turned on, the readout noise will be largely decreased (as low as 1.2e), and the dynamic range is basically unchanged.

Reliable Mechanics

There are four screws on the camera that seal the sensor chamber. This kind of design has been extensively tested and is very stable. Even when used in higher humidity environments, ASI294MM Pro will still work fine without dew problems.

The anti-dew heater power is around 5W and can be turn off in software to save power.

QE Value

As ZWO’s latest BSI (backside illuminated type) mono camera, ASI294MM Pro has very high QE performance, not only higher than its color version, but even ASI1600MM Pro. It is estimated that the QE peak value is about 90%.

ASI294MM-P vs ASI1600MM Pro

Two-Stage TEC Cooling: Ultra-Low Dark Current

ASI294MM Pro uses two stage TEC cooling that can lower the CMOS sensor temperature to 35c~40c below ambient, which can greatly reduce dark current generation and sensor noise even with extended exposure times.

The unique dark current suppression technology can even further reduce dark current noise. When it’s cooled to -20℃, the current noise can be as low as 0.0022e/s/pix, which is completely negligible!

Please notice that the camera needs to be connected to an external 12v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-15V to power the camera.

USB3.0 & 256M DDR3 Memory

The ASI294MM Pro is equipped with a USB 3.0 transmission interface and a built-in 256MB(2Gb) DDR3 cache to ensure stable and secure data transmission. Under long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.

Using the Sony IMX183CLK-J Mono Sensor with high resolution 2.4 μm pixels, it includes a 256MB DDR3 memory buffer.

 ASI183 QE peak reaches a remarkable 84%. In Ha channel, QE is still over 60%.

DDR Memory Buffer

The ASI183 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

Astrophotography Performance

The ASI183 cameras has a very large full well capacity（15000e） for such small pixel size, 1.6e read noise @ 30DB, and 12stops dynamic range @ Gain=0. The ASI183 cameras also utilize firmware features to minimize amplifier glow for maximum performance in astrophotography.

Reliable Mechanics

ASI183 Pro has same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.

Even when used in higher humidity environments, ASI183 Pro will still work fine without dew problems.

ASI585MC/MM Pro is a new ZWO deep sky camera based on the 4k SONY CMOS sensor with a 1/1.2″ format and 2.9μm pixels. It has a super high sensitivity and a large resolution of 3840*2160 (8.29MP in total). It also features high transmission speeds – In high-speed mode, the fast frame rate can reach 47fps with low read noise at full resolution! It also features a high SNR and high sensitivity, especially in near-infrared wavelength. Being an entry-level DSO camera, it offers great advantages of high cost-effectiveness.

Note：

External power supplies are needed for all ASl-cooled cameras. We recommend you use a 12V@3A~5A DC adapter (D5.5×2.1mm, center pole positive) or a lithium battery with 11-14V to power the camera. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.

Why Choose ASI585MC/MM Pro?

One Camera for All

The STARVIS 2 technology brings ASI585 Series more advanced imaging performance compared to other cooled cameras. Its high frame rate makes it not only suitable for DSO photography but also solar/lunar/planetary photography.

Large Full Well Capacity

The back-illuminated structure improves the camera’s full well capacity. Even with unbinned 2.9μm pixels, ASI585 Series has a full well capacity of 40ke-, nearly 3 times that of the last-generation sensor IMX485. A larger full well capacity gets the camera higher efficiency in collecting light, can effectively restrain the highlight area from being overexposed, and also can improve the signal-to-noise ratio.

Zero Amp Glow

ASI585 Series exhibits extremely clean dark frames with zero amp glow! No matter how long the exposure and how high the gain value is, you can easily get clean and smooth astro images!

Note: This feature is implemented directly at the hardware level, it does not require software control.

512MB DDR3

ASI585 Series uses a USB 3.0 interface, along with the built-in 512MB DDR3 cache, ensuring high-speed, smooth, and stable data transmission.

USB 3.0 Port & USB 2.0 HUB

USB 3.0 Port: Provides 5Gb bandwidth to allow ASI585 to run at 47fps at 8.29MP full resolution (10bit, high-speed mode).
USB 2.0 HUB: Can be used to connect various kinds of USB devices such as EFW, guide camera, and EAF.

Two-stage TEC Cooling

Thanks to the two-stage TEC cooling, ASI585 Series can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.

*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would decrease.

Below is the dark current curve of ASI585 Series at the temperature from -20℃ to 30℃.

Low read noise, High dynamic range

The camera has a built-in HCG mode, which can effectively reduce read noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain.

When the gain reaches 252, the HCG mode will be automatically turned on and the dynamic range reaches a level close to 11bit. The read noise in this case can be as low as 0.7e.

QE (Quantum efficiency)

Based on our testing results, the QE peak value of ASI585 is 91%.

Main Features:

Anti-dew

ASI6200 Pro comes with the polyimide heater that can avoid any dew problems.
The anti-dew heater which completely fit the protective window will heat it to avoid any dew problems.

Full Frame format

The ASI6200 Pro camera uses a full-frame format. The outstanding 9576x6388 resolution provided by the onboard Sony IMX455 sensor makes this camera a 61.2-megapixel full frame powerhouse! The sensor length and width are 36mm x 24mm respectively, and the diagonal is 43.3mm. This is a camera with a small pixel size of 3.76um that can accommodate a large well depth of 51.4ke.

Native 16bit ADC

ASI6200 Pro camera is our first batch of CMOS astronomy cameras with true 16-bit ADC. It is not a CCD-style 16-bit ADC – it really can achieve a dynamic range output of 14 stops. This significantly improves the image sharpness and contrast, and the contrast gradients are smoother and more natural-looking.

Sony EXview HAD CCD II ICX825 sensor - Super Sensitive

The fact that you're reading this this shows you've made it past the most common trap in choosing a camera for astroimaging - how many megapixels is it?

There are 2 variables in your camera that are far more important to consider when imaging faint deep sky objects. Sensitivity and noise.

The sensitivity tells us how many precious photons will be converted to signal...this is were the new Sony ICX825 shines! But how much more sensitive is it? Compared with Atik's previous 314L+ at 650nm, the 414EX is 60% more sensitive. In fact, the 414EX is even more sensitive than the already spectacular 460EX, making it the perfect camera for the enthusiast with a limited budget. The graph below shows the striking difference between the ICX285 and ICX825:

Low noise and effective cooling

Atik's 414EX has more than just great sensitivity.

Another feature of the 414EXmaking it a winner for astrophotography is it's exceptionally low noise. When capturing a stunning portrait of your favourite deep sky target you will understand how delicately faint it is. This means the data you wish to capture is sparse.

If the electronics of the camera add noise (unwanted signal) to your image the end result will be lacking in detail and contrast. To ensure the contribution from noise is minimised Atik's 414EX has thermoelectric cooling that can easily lower the CCD chip to 30ºC below ambient, and is regulated, so that your image calibration is consistent. This results in a noise level so low that for most applications dark frames are an option rather than a requirement. The upshot is that you can spend more time imaging!

The QHY294 Pro is a 4/3-inch back-illuminated camera, equipped with Sony IMX294 (Color) and IMX 492 (Mono) sensor. The 294 Pro has 11.7 MP at 4.63um, 14-bits A/D. The IMX294 and IMX492 chips have 46.8 million 2.315um pixels, which Sony 2×2 bins on-chip to create the sensor’s advertised 11.7 million 4.63um pixel array. The QHY294 Pro series camera is capable of locking and unlocking the on-chip binning to provide two readout modes. The first mode reads the sensor “locked” mode to produce 11.6mp images with 4.63um pixel size and 14 bits per pixel. The second read mode unlocks the binning to produce 46.8mp images with 2.315um pixel size at 12 bits per pixel.

The QHY294 Pro CMOS sensor has a dual gain mode, HGC (high gain) and LGC (Low gain). The QHY294 Pro will switch the two modes automatically when the gain is set to 1600 you will get the benefits of the ultra low read noise (1e- to 1.6e-) of the HGC mode and a full well capacity of about 14.5ke- at the switch point setting.

With the advantage of low readout noise and high-speed readout, CMOS technology has revolutionized astronomical imaging. A monochrome, back-illuminated, high-sensitivity, astronomical imaging camera is the ideal choice for astro-imagers.

The QHY268M/C is a new generation of back-illuminated CMOS cameras with true 16-bit A/D and 3.76um pixels. This new Sony sensor is an ideal CMOS sensor exhibiting no amplifer glow. 16-bit A/D gives high resolution sampling of the whole full well range. Digitizing 0-65535 levels yields a smooth image with continuous gradation of greyscale levels. The QHY268M/C is a cooled, back-illuminated, CMOS camera based on the Sony IMX571 sensor with native 16-bit A/D and 3.76um pixels.

1GB DDR3 image buffer

In order to provide smooth uninterrupted data transfer of the entire 26MP sensor at high speed, the QHY268 has 1GB DDR3 image buffer. The pixel count of the latest generation of CMOS sensors is very high resulting in greater memory requirements for temporary and permanent storage. The QHY268 has adopted a large-capacity memory of up to 1GB. Data throughput is doubled. This large image buffer meets the needs of high-speed image acquisition and transmission of the new generation of CMOS, making shooting of multiple frames smoother and less stuttered, further reducing the pressure on the computer CPU.

Internal Humidity Sensor

QHY268M has a unique internal humidity sensor (while QHY268C doesn’t). The Blue curve shown below represents humidity.

Native 16 bit A/D: The new Sony sensor has native 16-bit A/D on-chip. The output is real 16-bits with 65536 levels. Compared to 12-bit and 14-bit A/D, a 16-bit A/D yields higher sample resolution and the system gain will be less than 1e-/ADU with no sample error noise and very low read noise.

BSI: One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor. In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.

Zero Amplify Glow: This is also a zero amplifer glow camera.

TRUE RAW Data: In the DSLR implementation there is a RAW image output, but typically it is not completely RAW. Some evidence of noise reduction and hot pixel removal is still visible on close inspection. This can have a negative effect on the image for astronomy such as the “star eater” effect. However, QHY Cameras offer TRUE RAW IMAGE OUTPUT and produces an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.

Anti-Dew Technology: Based on almost 20-year cooled camera design experience, The QHY cooled camera has implemented the fully dew control solutions. The optic window has built-in dew heater and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew and the sensor itself is kept dry with our silicon gel tube socket design for control of humidity within the sensor chamber.

Cooling: In addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise.

The Atik 383L+ is an 8-megapixel camera using the Truesense KAF-8300 CCD. Much has been written about this CCD to justify its place in astronomers' hearts. It can be succinctly summed up by saying that it's a fabulous CCD, with a huge number of good-sized pixels, and is currently available at an irresistible price.

This sensor has redefined mid-range astro-imaging, making multi-megapixel cooled cameras much more accessible.

Atik prides itself on providing cameras offering the very highest image quality at a reasonable cost. They have built on the success of the highly-regarded Atik 314 platform to support Kodak's KAF-8300. This immediately offers a huge number of advantages, including the very low read-noise circuits and the reliability of using this established design.

Mechanical Drawing

Quality hardware

The key to any high-quality camera is the ability to convert light collected by the sensor into digital information while ensuring that as little noise as possible is added. The digital image needs to truly reflect the light collected. The Atik 383L+ achieves this, by having:

• Very low read-noise, 7 electrons, on par with many Sony sensors, enabling faint details to be detected.
• Great linearity, with a regression correlation coefficient of R = 0.9998 over the range of 1,000 to 64,000, making the camera suitable for sensitive photometric measurements.
• The bias frame histogram from the camera shows the ideal Gaussian shape, indicating that maximum detail can be extracted on processing.

The Atik 383L+ is a dream combination of low-noise electronics and a scientific-grade sensor that we are able to offer at a fantastic price. Whether you are an established imager or are just starting, the Atik 383L+ is a great choice.

Instruction Manual

The Atik 16200 Monochrome camera has been designed from the ground up around the KAF-16200 sensor. With a diagonal measurement of 35mm (APS-H format) and 6 μm pixels this camera is an incredible mix of high resolution and sensor real estate.

It is a great match for a range of telescopes, and all at a much more accessible price than the likes of KAF-11002 and KAF-16803 based cameras.

Aluma CCD cameras measure just 4.25″ x 4.25″ x 4.0″ with handles (3.5″ without handles) and weigh just 2.2 lbs (1 kg).

Even-Illumination Shutter

All Aluma CCD cameras include a mechanical shutter, which is used for both dark/bias calibration frames and for shuttering exposures on full frame sensors. Rather than using a complex iris shutter, which are prone to failure, the Aluma CCD uses a twin vane shutter and direct drive motor for high repeatability, reliability, and extremely long life.  The shutter is designed to be “even illumination” for the best accuracy in photometric measurements.

The left image shows a flat field image taken with a camera using an iris type shutter. The right image is a flat field image taken under the same conditions using our even-illumination shutter.

The two-stage cooler, powerful fans, and advanced heat sink designed using thermal flow simulation combine to produce a typical cooling delta from an ambient of -50C. This is quite a feat considering the Aluma CCD’s very compact and lightweight package.

SmartCooling automatically adjusts the fan speed to optimize cooler performance and power consumption. The camera’s firmware is constantly monitoring the sensor and heat sink temperatures and controlling the cooler power. When full cooling power is needed – when ramping down or running near full power – the fans ramp up to their maximum speed, resulting in the strongest possible cooling. When less cooling power is needed the fans automatically slow to reduce noise levels and power consumption. SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.

Positive detent mechanism provides single-pixel filter position accuracy

Precision flat-fielding with utlra-accurate indexing

The above left image shows a dust spot on the filters. A flat-field calibration frame was taken, then the filter wheel was rotated several times before taking a second picture, which was flat-field calibrated, above right. No evidence of the dust spot is visible. This high precision results in the highest quality images and excellent photometric accuracy.

The Aluma wheel holds standard 36 mm filters, and inserts are available for 1-1/4″ filters, which are suitable for smaller format CCD sensors.

The Aluma filter wheel replaces the camera’s front plate, resulting in the minimum possible back-focus, ensuring that the camera / filter wheel combination will reach focus on the widest possible variety of optical systems.

Optional StarChaser SC-2 Off-Axis Guide Camera

For astronomical imaging the Aluma CCD series works the StarChaser SC-2 Off-Axis Guide Camera. This provides reliable guiding with no impact from optical train flexure. It also supports the operation of the optional AO-8A Adaptive Optics accessory.

Optional AO-8A Adaptive Optics

All Aluma CCD models can operate with the AO-8A Adaptive Optics accessory. The AO-8A uses a tip-tilt window to quickly and precisely adjust the image position in response to autoguider feedback. With Adaptive Optics there is no backlash, stiction, or lag, and the movements are extremely precise and accurate. This allows the AO-8A to not only remove the effects of periodic error, drift, and wind gusts, but also reduce the effects of atmospheric seeing

Using SONY’s best-in-class CCDs, you’ll get the precision and ultra-clean images of a CCD with the sensitivity of CMOS technology.

Aluma CCD 694 – Incredible Sensitivity

The ICX-694 CCD is one of the best optical sensors ever produced, with peak quantum efficiency over 75%, very broad spectral sensitivity, and extraordinary blue sensitivity. It also has very low read noise, large dynamic range, and extremely low dark current. This combination of high sensitivity and very low noise means you get cleaner, deeper images – faster.

• Bulletproof firmware update capability – virtually impossible to “brick”

Advanced Software Included

All Aluma CCD models ship with MaxIm LT for Windows – a special version of MaxIm DL specific to our cameras. Aluma CCD also supports third-party applications through ASCOM and native drivers.

Compact and Lightweight Design

Aluma CCD cameras measure just 114mm x 114mm x 102mm with handles (89mm without handles) and weigh just 1 kg(2.2 lbs).

Mechanical Shutter

The SBIG Aluma CCD 814 has electronic shuttering, allowing a minimum exposure of just 0.001s. In addition, it has a high-reliability mechanical shutter, which facilitates accurate dark/bias calibration frames.

High-Performance ICX-694 Image Sensor

The Aluma CCD 694 uses the popular 6-megapixel SONY ICX-694ALG sensor. This sensor has 2750 x 2200 pixels at 4.54 microns square, for a 14.6 mm x 12.8 mm chip size.

This is a high-sensitivity interline CCD sensor with an extremely low dark current and very low read noise. Combining this high-performance sensor with Aluma CCD’s high cooling performance and low readout noise results in exceptionally clean images.

This sensor includes microlens technology that concentrates light on the sensitive area of each pixel. The CCD’s sensitivity peaks in the center of the visible spectrum at 550 nm, and maintains high sensitivity throughout the visible spectrum. The ICX-694 is particularly good in the blue compared to other sensors on the market.

SmartCooling^TM

All Aluma CCD cameras include our powerful new SmartCooling technology. The two-stage cooler, powerful fans, and advanced heat sink designed using thermal flow simulation combine to produce a typical cooling delta from an ambient of -50C. This is quite a feat considering the Aluma CCD’s very compact and lightweight package.

SmartCooling automatically adjusts the fan speed to optimize cooler performance and power consumption. The camera’s firmware is constantly monitoring the sensor and heat sink temperatures and controlling the cooler power. When full cooling power is needed – when ramping down or running near full power – the fans ramp up to their maximum speed, resulting in the strongest possible cooling. When less cooling power is needed the fans automatically slow to reduce noise levels and power consumption. SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.

Advanced Software Included

All SBIG cameras come with our MaxIm LT software – a US$200 value! MaxIm LT is a special version of our venerable MaxIm DL software that provides complete control of your camera, filter wheel, and autoguider, plus advanced image processing capabilities. If you wish you can upgrade to MaxIm DL Pro to get complete observatory integration and even more processing and analysis capabilities.

Included Accessories

Each Aluma CCD camera package includes:

• MaxIm LT software – please use this form to request your license
• Deluxe carrying case
• Universal power supply (110V / 220V, 50-60 Hz)
• 2″ Nosepiece adapter
• USB flash drive containing software, drivers, and documentation
• 15 foot (4.5 m) USB cable

Optional Micron-Precision Filter Wheel

The optional FW8S-Aluma 8-position filter wheel includes a positive centering mechanism that precisely centers each filter in the exact same position every time. This single-pixel accuracy completely eliminates ghost images of dust spots and other artifacts after flat fielding.

Positive detent mechanism provides single-pixel filter position accuracy

Precision flat-fielding with utlra-accurate indexing

The above left image shows a dust spot on the filters. A flat-field calibration frame was taken, then the filter wheel was rotated several times before taking a second picture, which was flat-field calibrated, above right. No evidence of the dust spot is visible. This high precision results in the highest quality images and excellent photometric accuracy.

The Aluma wheel holds standard 36 mm filters, and inserts are available for 1-1/4″ filters, which are suitable for smaller format CCD sensors.

The Aluma filter wheel replaces the camera’s front plate, resulting in the minimum possible back-focus, ensuring that the camera / filter wheel combination will reach focus on the widest possible variety of optical systems.

Optional StarChaser SC-2 Off-Axis Guide Camera

For astronomical imaging the Aluma CCD series works the StarChaser SC-2 Off-Axis Guide Camera. This provides reliable guiding with no impact from optical train flexure. It also supports the operation of the optional AO-8A Adaptive Optics accessory.

Optional AO-8A Adaptive Optics

All Aluma CCD models can operate with the AO-8A Adaptive Optics accessory. The AO-8A uses a tip-tilt window to quickly and precisely adjust the image position in response to autoguider feedback. With Adaptive Optics there is no backlash, stiction, or lag, and the movements are extremely precise and accurate. This allows the AO-8A to not only remove the effects of periodic error, drift, and wind gusts, but also reduce the effects of atmospheric seeing

SBIG Aluma CCD 694 Instruction Manual

With the advantage of low readout noise and high-speed readout, CMOS technology has revolutionized astronomical imaging. A monochrome, back-illuminated, high-sensitivity, astronomical imaging camera is the ideal choice for astro-imagers. The QHY600M-L uses the latest SONY back-illuminated sensor, the IMX455, a full frame (35mm format) sensor with 3.76um pixels and native 16-bit A/D. This sensor is available in both monochrome and color versions. The QHY600M-PH SBFL ends the days of non-16bit CMOS cameras and it ends the days non-full frame (and larger) monochrome CMOS cameras.

The QHY600M-L has extremely low dark current (0.002e/p/s@-20C) using SONY’s Exmor BSI CMOS technology. QHY600M-PH SBFL is also a zero amplifer glow camera. The QHY600M-PH SBFL has only one electron of read noise at high gain and full resolution and 4FPS readout speed. One electron of read noise means the camera can achieve a SNR>3 at only 4 to 6 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc., making this large area sensor ideal for sky surveys, time domain astronomy, fluorescence imaging, DNA sequencing and microscopy.

Models

QHY600 Series have mutiple models which covers both photographic and scientific using. Below list different types of QHY600 PH (photographic) series:

QHY600PH : Standard version for amateur astrographers;

QHY600PH-SBFL (Short back-focal length version) ：specially designed for DSLR lens users or those who has special requirment of short back focal length. This version has a special front part version which has 14mm B.F.L only (The B.F.L consumed equals 12.5mm when connecting QHYCFW. About the defination of “BFL Comsumed” and our adapter system please view: https://www.qhyccd.com/astronomical-camera-adapter-bfl-solution/). QHY600SBFL can easily match Canon/Nikon lens even with filter wheel. On the side of this adapter there is a 4mm hole to connect air pump through plastic pipe in case of the dewing glass when necessary.

QHY600L : a lite, shorter and cheaper version.
