Sensor: Mono IMX533 CMOS
SV605MC is designed with a diagonal 15.968mm （Type 1）CMOS sensor with a mono square pixel array and 3.76μm x 3.76μm per pixel. The sensor incorporates 14 bit A/D converter, the 14-bit digital output makes it possible to readout the signals of 9.07M effective pixels at high-speed of 20 FPS. Read out noise is as low as 1.0e which makes sure the highly suitable for high definition, low noise deep space objects imaging.

Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell tale signs of ‘amp glow’. As the SV605MC uses better zero amp glow design, The glow was not visible during the 300 second exposure, make sure the totally high quality“dark”image.
-
Cooling System
Thanks to the two-stage TEC cooling, the SV605MC can lower the CMOS sensor temperature to 30 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during longer exposure times. The temperature is not the lower, the better, and when the sensor’s temperature is between -5℃~ 5℃, the camera performs better.

USB 3.0 & 256MB DDRIII Buffer
The SV605MC features a USB 3.0 data transmission interface and a built-in 256MB DDR3 high-speed memory for fast and efficient deep-sky objects imaging, and to buffer image data and ensure stable data transmission.
-
Compatible Systems
SV605MC supports systems: Windows, Linux OS, Raspberry Pi, Mac OS, Chrome OS. All software and drivers for this camera are available from the manufacturer’s website. Note: 1) The configuration of desktop computer is not less than Intel 4 generation i5, and the memory is not less than 4G. 2) Laptop configuration is not less than Intel 6 generation i5, memory is not less than 8G.
-
Support ROI & BIN
The SV605MC camera has ROI and BIN functions. Any resolution can be set while keeping the image scale of the imaged object unchanged, greatly improving the rate of photography. BIN1*1, 2*2, 3*3, 4*4 pixel can merge adjacent pixels, improving camera sensitivity.

SV605MC-Our first deepspace mono cooled camera, with a diagonal 15.968mm （Type 1）CMOS sensor with a mono square pixel array and 3.76μm x 3.76μm per pixel. The sensor incorporates a 14-bit A/D converter, the 14-bit digital output makes it possible to read out the signals of 9.07M effective pixels at a high speed of 20 FPS. Read-out noise is as low as 1.0e which makes sure the highly suitable for high definition. now we have started to receive feedback from customers, let us take a look at these early feedbacks, if you happen to be following them, then I hope the following comments will be helpful for you. Steve Wainwright Click on an image to get a closer view. Implementing and testing a prototype SV605MC monochrome, cooled camera in AstroDMx Capture for Windows with an Altair Starwave ASCENT 60ED doublet refractor with an 0.8 reducer/flattener and an Altair quadband filter. Implementing and testing a prototype SVBONY SV605MC monochrome cooled camera.
An
SVBONY SV605MC monochrome 14 bit camera was placed at the focus of a
Coronado Solarmax II, 60, BF15 H-alpha scope mounted on a Celestron AVX
mount.
AstroDMx Capture for Linux was used to capture a 5000 frame 8 bit SER file at a resolution of 1240 x 1270.
The best 95% of the frames in the SER file were stacked in Autostakkert!
The resulting image was wavelet processed in Registax 6 and post processed in the Gimp 2.10.
 Yanesh Bishundat I finally got to use the sv605mc and tried to do a side by side comparison with the sv605cc camera. The monocam is really in a league of its own! in january i managed about 3 hours of exposure time with the sv605cc and day before yesterday I tested the monocam using only 20mins of integration time in each filter (Ha/SII/OIII) to try to get a comparable result using the monochrome camera vs the one shot color camera from SvBony. Apologies in advance for the slight out of focus image with the sv605cc as i only used a bahtinov mask for focusing, whereas in the mc camera i used HFR in nina to focus. The first one is with the osc camera and the second one is with the mc camera. The third one is with approx 3hrs of data.

I got the SV605MC and I've been trying to test it, but wind/clouds/rain season started and I have not been able to have a proper capture session. I usually take pictures with my Canon SL3 and Celestron 6SE, now I also have an SV503 102ED. My intent is to compare how pictures would look with a similar capture time, using both cameras on both the Celestron 6SE and SV503 102ED. This might give some references for people that want to jump from DSLR to astro-dedicated cameras, coming from a person that just made the jump himself. Anyways, weather has other plans and so far I've only been able to take ~40 minutes worth of data, at a Bortle 3-4 location. I might have over processed a bit the image with the little data I have; I also found what I've seen described as "banding" on my darks, that I could only remove denoising the combined stacked picture (I haven't encountered this effect before with the DSLR). My mount was behaving, so these were unguided shots... Overall, not the best conditions 😅. This might be too little capture time to make an educated opinion, but so far I'm happy I at least got the camera working in my setup. Will keep trying testing and come back with a more thorough post.

SV605MC First Impressions: The post is a JPG, so a little quality is lost in the post I received the camera just over a week ago and finally had some marginally clear skies. I spent the time doing a sensor analysis and creating some flats using Sharpcap. This is just my first test and will be doing much more in upcoming days (as the weather permits). Much like the 605CC, the camera comes in a zippered case with a variety of spacers, a 1.25" filter adapter, some extra dessicant and a tool. The sensor analysis is below, both 8 and 16 bit. The results were similar to the 605CC analysis, which makes sense since the sensor is the same in each camera. I know some people do not like the square 3008x3008, I find it good to work with and it allows for more options when cropping (in my opinion). For the first test, I just worked with a basic greyscale image, no color filters. I used as my target M51. The camera has the same good build quality, and I did not see any dust or debris from manufacturing, and the flats were very clean. I am using an 8" Newtonian Reflector, Skyview Pro Goto mount, SV106 Guide scope and ASI120mm-s guide camera. I also have an Sv305 that I use for guiding at times. PHD2 for guiding, Bortle 4/5 skies I used SharpCap and just used the Smart Histogram function for this first test. 18.3 seconds exposure, and I was somewhat surprised that the Unity Gain was 135, as opposed to 125 for the 605CC. My focus position was almost identical to the focus for the 605CC, so I was able to start imaging relatively fast after the clouds finally cleared totally! 120 lights 20 Darks 40 Flats\40 Bias I know some will say that the IMX 533 doesn't need darks because of the lack of amp glow, but there is some ambient light in my neighborhood, so I still use darks. I stacked all in DSS, and stretched in PixInsight. I did not use any noise reduction, and I was surprised how clean the image was. The cooling was efficient, and mostly stable, I set the temp at 0 degrees, and it stayed close to that, drifting a little lower over the course of the test, down to about -.6, but considering the heat in north Florida, overall I was pretty pleased. The cooler averaged 65% power, but was quiet and virtually no vibration. So below is the first test photo as well as my sensor analysis, will be starting the LRGB tests this week. Videos and more detail to follow.  |
