New Svbony SV305C Camera, Best For Planetary and DSO Imaging!
"In my opinion, I think this camera really is of excellent value and I am sure many astronomers with better equipment than mine and under much better sky conditions can get much better results out of this new little gem of a camera from Svbony. Keep in mind this camera costs around $160 US only! The competitors with similar IMX682 based cameras to this one cost twice the price as Svbony!"

sorry forgot there is one other bug I hope the tech team can fix. When you change the exposure in Sharpcap the saturation settings sets to 0 (none) from whatever settings you have it on. I recently discovered this one a few nights ago.

Thank you very much for your feedback and suggestions. We have already connected with the technical team, hoping to improve and bring a better experience to users

Haha that is my comment Sara from my review I made haha. This camera overall is great and I have used it several times now outside for both planetary and DSO imaging and have got several nice images from it. Having said that like any new camera that hits the market there are a few glitches in the driver for this camera (I have verfiied this with Nicola the developer of AstroDMX in several conversations and both of us testing each issue). Bug 1: it seems if you cancel during a Sharpcap dark frame capture during the dark frame creation process the whole capturing software will lock up and you literly need to reboot your computer as you will get another error if you try to just disconnect and reconnect the camera (cannot iniitalize). I think this bug has happened previously on some drivers with some other cameras (like the older SV305) in the past. it is currently happening with the SV305C. Bug 2: it you quickly change resolutions and or the gain while imaging such as during planetary imaging when you want to use the ROI mode and you have to reduce the resolutiion quickly sometimes (not all the time) the camera (and driver I guess) will stop capturing frames (and will be dropped all of a sudden) in Sharpcap and Astrodmx. You have to unplug and replug the camera and reconnect to fix this to continue. 3. Not really a bug but for some strange reason and I am not sure why the camera only captures at a top maximum 53tps even well above the lowest roi mode. For example when I get to about 800 by 600 ROI mode I am already recording at 53 tps (3 to 5 ms exposure) but if I go down to 320 by 200 resolution mode if still remains at 53fps max. I would expect as you reduce resolution (less pixels) that the frame should keep speeding up not sure why it does not (all other planetary cameras I own do). Not sure if this is a hardware thing or a driver limitation causing the max speed or not. Other than that this new camera works pretty good and I have got some decent DSO and planetary images from it so far (see facebook Svbony group, my blogs and reviews). I do wish the Svbony tech team on their next driver update release would change the current HCG value (I think at 253) to a lower value (say 150 the best or 203 next best) as this would really help the full well capacity during imaging and reduce noise the noise floor consideribly at the optimal gain and noise values for this camera (see charts for Sony IMX662). I hope this helps and if can be assistance let me know Grant.
