Introducing the ZWO ASI585MC-PRO USB3.0 Colour CMOS Camera with 2-stage TEC cooling.

Now with this new cooled model, this is definitely the beginner's "do it all" astro photo OSC cameras? Planets, Moon, deep sky or infrared imaging? No problem!

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 47ke-, nearly 4 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.

Zygo Interferometer Testing For ED Refractor Telescopes!

We are extremely pleased to announce our Zygo Interferometer is now installed and ready for use! Our experienced staff can test refractor lenses up to 120mm aperture and provide a comprehensive 2 page report showing the optical quality and Strehl ratio, plus much more information. We are using the very latest Zygo MX software to provide a more detailed report compared to other standard reports.

 

The interferometer is essentially a measuring instrument. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. From this, we can adjust the position of the test optic and the reference sphere to obtain a perfectly calibrated system. The more central the laser to the test optic and then on return, the better and more accurate reading and measurement we can take. This takes a lot of adjustment to get the best results from the optical surface. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. Continue reading for an explanation of the individual values and you can also see a test report that was done on one of our RVO Horizon 60 OTAs. 

We are offering certain telescopes with a Zygo test at an extra cost. Mainly ED doublets and triplets. All available telescopes with a Zygo test report are listed here. Just select Zygo Test Report from the drop down box at the top of the listing and we will test the optics in house and provide a full 2 page report with your scope. This will show you the optical quality of your telescope optics. We can also offer this service on your refractor telescope. Please get in touch for more details about this. 

At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope.  We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. 

Other measurements such as the PV and RMS are important too. With these measurements, the lower the number the better as it shows less curvature on the lens. The flatter an optical lens, the better it will perform. The PV rating (Peak To Valley) is a measurement from the highest point (Peak) to the lowest point (Valley). From this we get the RMS (Root, Mean, Square). This is a similar figure to the PV and measured exactly the same way. The RMS is basically an average height difference from the PV so again, the lower the better. As you can see form the example below, we measured an RMS of just 0.027 wave which is a very good value.

We also measure the Power with our systems which is essentially the error from the reference sphere to the test optic. The reference sphere we use on our system is a very high quality sphere so the closer to zero the Power, the less error between the 2 elements thus ensuring a higher quality optical surface. 

You will also see some more values such as Astigmatism and Coma. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The lower the number, the less of these aberations you will effectively see but with most refractors, you can buy field flatteners which will compensate for the coma anyway. The astigmatisms value is explaining the error between the symmetrical curvature of the lens. Basically, no lens will be perfectly symmetrical, the lower the astigmatism, the more symmetrical the lens surface is. 

Once the Zygo test report has been completed, the optical alignment is thoroughly tested and tuned to ensure they are spot on before they leave us. 

All available telescopes are on the website at the link below and ones we've tested already that are available straight away are also listed.

Here is an example of the test what we provide. This was a test on one of our Horizon 60 ED OTA's.
