I am using a core I3 6100 @3.7Ghz with 8GB ram, should be good enough.
I am currently capturing, memory usage is about 33% CPU is 3% while guiding, but I will keep an eye on it while downloading
edit : while downloading, the CÜ usage rises to 35%. CCD inspector also automatically analyses the image.
Now the CPU clock is about 800Mhz, due to the very light CPU load. Sometimes, a too low clock or too agressive energy saving settings, could slow down the USB speed, but I never saw that before on USB2 camera, only on USB3 camera and for planetary imaging, whith a huge data flow.
I will try to increase a little bit the minimum cpu clock in windows parameters, lets say from 5% to 10% min
Another thing that I suspect : the USB2 / USB3 compatibility. I don’t know for the G3, but I saw some Atik camera (the 460 for instance) that don’t work well on USB3 ports thought there is not any error in windows. The same camera on the same PC work well on native USB2 ports.
edit 2 : I see 2 ascom driver installed : the 32 bits version and the 64 bit version. Don’t know why both are installed nor it could have an impact (I am a member of a team and the PC is at a remote observatory. I am fine tunning the setup)… We are also using a G1 guide cam.
The PC is running win 10/64, latest moriavian drivers, ascom 6.3, latest SGP
