The QHY5III462 camera uses the Sixth Generation Sony 2.1 megapixel IMX462 STARVIS CMOS sensor. The pixel size is 2.9um 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 QHY5III462 is USB 3.0 powered and controlled. No additional power is required.

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 (Super High Conversion Gain) for very low read noise at high gain. This is ideal for stacking hundreds or thousands of short planetary images. Second, it is exceptionally sensitive in the NIR.

In this latest generation of sensors, the photodiode portion of the pixel well is physically deeper than in previous Sony BSI sensors, allowing photons of longer wavelength to penetrate deeper into the substrate. This dramatically increases the sensor’s sensitivity to red and near infrared (NIR) light. 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 as the peak QE in the visible wavelengths. For planetary imagers using a methane filter that passes light around 880nm this is welcome news.

BSI

One benefit of the back-illuminated CMOS structure is improved sensitivity. 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.

Extended Near Infrared Sensitivity

Logically, one would think, each generation of Exmor sensor would be built upon and incorporate all of the improvements of the generation immediately preceding. However, this was not the case with the fifth generation Exmor R sensors.

The first back-illuminated sensors used shallower pixel wells (like the third-generation front- illuminated designs) than the physically deeper pixels of the fourth generation. So, while the back- illuminated structure increased the sensitivity in the visible range by 2X, the shallower pixels did not improve the NIR. The answer to this is seen in the latest, sixth generation, Sony Exmor R sensors, like the IMX462. Using physically deeper pixels in conjunction with the back-illuminated structure has dramatically improved the sensor’s sensitivity to both the visible and near infrared wavelengths.

sHCG Mode

Another advantage of the QHY5III462 is the camera’s “Super High Conversion Gain” capability. By using a lower capacitance, a small amount of charge can be converted to a high voltage resulting in higher sensitivity in low-light conditions. The readout noise of the QHY5III462 in high gain mode is as low as 0.5 electrons!

The test exposures below demonstrate the low light improvement over the IMX290 sensor. The QHY5III462C image is on the left and the corresponding QHY5III290C image is on the right. The low light conditions and exposures are identical for each top and bottom pair of images and a UV/IR filter was in place for each camera. So this test demonstrates the QHY5III462C’s increase in sensitivity and SNR over the QHY5III290C under the same conditions in the visual light spectrum alone.

Color and Mono Imaging

The filter matrix in the IMX462 uses organic dye filters. These filters are very efficient at visible wavelengths but become completely transparent in the NIR. For this reason, good RGB color balance requires an external UV/IR filter that blocks NIR wavelengths.

Many color cameras build this UV/IR filter into the camera or optical window for normal color imaging. However, in order to fully exploit the capabilities of the 462C sensor, in the QHY5III462C camera the optical window is AR coated only with no UV or IR blocking. Instead, the QHY5III462C camera includes 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.

Specifications

Camera Curves

ASI585MC 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 at full resolution! 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. You can also use ASIAlR to power the cameras. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.

One Camera for All

The STARVIS 2 technology brings ASI585MC Pro 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.

STARVIS 2

STARVIS 2 was developed by SONY and evolved from STARVIS. It is the latest technology with a wider dynamic range and super-high sensitivity beyond the human eye. Benefiting from it, ASI585MC Pro’s sensitivity and signal-to-noise ratio is greatly improved.

Large Full Well Capacity

The back-illuminated structure improves the camera’s full well capacity. Even with unbinned 2.9μm pixels, ASI585MC Pro 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

ASI585MC Pro 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

ASI585MC Pro 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 ASI585MC Pro 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, ASI585MC Pro 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 ASI585MC Pro at the temperature from -20℃ to 30℃.

Camera Performance

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 0.9e.

QE (Quantum efficiency)

Based on our testing results, the QE peak value of ASI585MC Pro is 91%.

Light pollution in the night sky can significantly degrade contrast in astronomical images. This is especially true when using very fast telescopes like the 8” RASA because the sky background saturates very quickly. The “noise” of the light pollution overwhelms the “signal” from the celestial object you are imaging, making it difficult to get the most detailed image.

The RASA 8 Light Pollution Filter remedies this by blocking light pollution while transmitting light from deep-sky objects. The result is bright, detailed objects that pop off the black sky background with superior contrast.

Fortunately, many sources of light pollution have relatively discreet emission spectra; they emit primarily at specific wavelengths of light. By strategically blocking these wavelengths, the filter greatly reduces the effects of light pollution without degrading overall image quality.

How it Works

The Light Pollution Imaging (LPI) Filter for the 8” RASA blocks light from some of the most common sources of light pollution between 400-700nm (i.e., the visible spectrum), including high- and low-pressure sodium-vapour streetlights, mercury-vapour streetlights, and natural airglow caused by oxygen in the atmosphere.

Unlike some light pollution filters, the LPI filter blocks only specific areas of the spectrum instead of wide regions. This helps to maintain image brightness and colour balance. In addition, specific wavelengths associated with emission nebulae, such as H-α(656nm), H-β (486nm), OIII (496nm and 501nm), and SII (672nm), are highly transmitted, ensuring minimal loss of image brightness for those objects.

The filter fits directly into the internal filter mount in the RASA 8’s front lens cell, where the optical window normally mounts. By removing the clear window and replacing it with the filter, optical performance for the entire system is maintained.

Each filter comes with a plastic storage case to safely store the filter or the placeholder glass that came with your RASA when not in use. You will also receive a spectral transmission graph unique to your specific unit, verifying its performance.

Up close & sharp – Samyang 135mm F2.0!

The Samyang 135mm F2.0 ED UMC II Canon EF Full Frame Camera Lens is a manual focus telephoto lens for full frame sensor sizes. It expresses vibrant colour and soft out-focusing area which makes it the best lens to shoot portrait, night scenery, wild-life and journalism photography.

This lens has a low F number of F2.0. You may control the lens precisely when shooting under various exposure environment including relatively dark or too bright situations.

This lens features 11 lenses in 7 groups especially including extra low dispersion lens (ED) to offer high resolution throughout the image. Ultra Multi Coating (UMC) is used by Samyang Optics to optimise the light penetration and minimises flare and ghost. With such optical construction, it has 0.8m of minimum focal length to film subjects in near distance. Also, the floating type design secures as much light as possible and maximises the resolution by minimising spherical aberration and distortion.

There are 9 aperture blades designed to be almost as a full circle when aperture is closed which expresses starlike ray clearly and beautifully. The frame of the lens is compact and solid since it is made of high-strength aluminium alloy so you can create trustworthy images. The detachable petal-shaped lens hood minimises flare and ghost by sheltering lens from unnecessary light.

ALP-T Dual Band 5nm Filter is best suited for optics f-ratios slower than f/3.6, the standard Antlia ALP-T Dual Band filter is highly recommended. Meanwhile, if you seek the best possible performance with any optics faster than f/2.2, the highspeed version is the best choice.

The Antlia ALP-T dual band 5nm series filter is a dual line-pass filter that was designed to be used primarily with one-shot color (OSC) cameras such as DSLR's and astronomical OSC cameras. It can also be used as a narrowband filter for monochrome cameras to save imaging time. The advanced multi-coatings on our ALP-T ultra dual-band filter effectively isolate the red Ha and the blue-green OIII lines light from emission nebulae, with almost total suppression of optical density (OD) 4.5 on unwanted wavelengths from light pollution, moonlight, and airglow. The result is that our ALP-T dual band 5nm filter creates a superior signal-to-noise ratio and better contrast in your images.

The Antlia ALP-T Dual Band filter enables the capture of the two main emission nebulae bands at the same time, whilst suppressing unwanted light pollution. It enables you to capture cleaner data and reduces the post-processing efforts to isolate faint details from the background light pollution.

Application and Performance:

Designed especially for optics, slower than f/3.6

Engineered specifically for use with DSLR, CMOS, and CCD color cameras

Suppression of optical density (OD) 4.5 on unwanted wavelengths adds signal-to-noise

Introducing the Starlight Xpress TRIUS PRO Series of cooled CCD cameras to our product portfolio.

The TRIUS range of cameras was introduced in 2014. These were the first cameras on the market to incorporate a powered USB 2.0 hub in the rear of the camera to enable the user to connect their USB filter wheel and guide camera directly to the camera rather than multiple cables back to the computer - simplicity and convenience.

The new TRIUS PRO Blue series follows on from that success. We have redesigned the electronics to give even lower read-noise figures and faster downloads. With the Sony CCD cameras, we are now getting read-noise figures that are better than most CMOS cameras (when used at unity gain), along with 16bit data and significantly better dark-noise figure thanks to the impressive cooling. Dark frames really are a thing of the past, making calibration frames optional rather than compulsory, giving you more time to capture data and process your images.

There's lots of advantages of using a CCD chip for deep-sky imaging compared to CMOS cameras. If you'd like to know more, read BINTEL's tech article here.

Please note this camera uses a "Grade 1" CCD chip.
