The Latest Feedback on SV605MC

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.

A month ago, we launched the testing plan for SV605MC, and 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.

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.

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.

The above comments are just for reference. At present, we have also received feedback about the problem of banding in the camera. We are working with the development engineers to solve it. If there is a latest software update, we will let you know as soon as possible.
