The ASI2600MC Duo combines imaging and guiding sensors in one compact body. The main sensor is the Sony IMX571 coming with a native 16-bit ADC,14stops dynamic range, and a 3.76um square pixel array. The readout noise is as low as 1.0e, and the full well capacity reaches an incredible level of 80ke. And it has no amp glow!

The guide sensor is the Type 1/1.8 SC2210 with excellent NIR sensitivity. The sensor size is 7.68mm x 4.32mm. It has 4umx4um pixels with an array of 1920×1080 and a full depth of 8780e.

The stars on the corner of the guide images affected by reducers back focus distance might not be very round. It is not due to the sensor tilt and will not affect normal use.

Tilt Adjustment from Rear (Optional)
The 3 points from the rear make tilt adjustment much easier without the trouble of removing the tilt plate from the camera.

Main sensor
The main sensor IMX571 features an APS-C format and 26MP total pixels. The size is 23.5mm in width x 15.7mm in height, and the diagonal is 28.3mm. The 3.76um x 3.76um small pixel size accommodates an impressive full depth of 50ke. With the new hardware technology, it is even extended to 80ke.

STARVIS technology
ASI2600MC DUO is based on Sony STARVIS technology. Sony’s back-illuminated CMOS image sensor improves sensitivity and noise reduction – the key factors to enhancing image quality.

Camera performance
Native 16bit ADC
This 16-bit ADC is not a CCD 16-bit ADC. It can really achieve a dynamic range output of 14stops, which will significantly improve the image sharpness and contrast, and also create smoother and more natural color transitions.

FPS
ASI2600MC Duo’s max FPS in RAW 8 mode at full resolution is 15FPS, which is even quicker compared to ASI2600MC Pro.

Extended full well mode
The full well capacity of ASI2600MC Duo is extended to 80ke, which is 1.6x larger than ASI2600MC Pro.

USB 3.0 & 512MB DDR3 buffer
With the match of USB 3.0 and 512MB DDR3 buffer, ASI2600MCDuo provides stable and secure data transmission that can effectively avoid frame-dropping issues during long exposures.

No amp-glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images. It is the tell-tale sign of amp glow. As the ASI2600MM Duo uses zero-amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.

Two-stage TEC cooling
Thanks to the two-stage TEC cooling, ASI2600MM Duo 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.

Anti-Dew heater
There is a polyimide heater completely fitting the protective window in the ASI2600MM Duo camera. It can help avoid any potential annoying dew or icing issues depending on the environment in which you capture images.

The power of the heater is around 5W. You are free to turn it off anytime in your photography software if you want to save power.

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.
