I thought the 8300 chip was a relatively narrow FOV. Its only a bit bigger than the ST10 and a lot smaller than a DSLR.
Smaller than that would be the ST2000 size cameras. They do not compare even vaguely in terms of performance having used both.
ST10 is a fabulous camera but still quite expensive. The 8300 does not have its sensitivity but has more pixels and is a clean chip and is cheap. There are numerous excellent images around using the 8300 chip in various cameras.
The real solution to imaging in heavy light pollution is narrowband. Ask Fred. Or you are limited to imaging the brighter objects which is fine as there are quite a few. You will also probably need to use shorter exposure times and become adept at gradient removal processing of which there are several techniques. Gradient Xterminator would be the most important processing tool you will use. Other gradient techniques will supplement the job Gradient Xterminator will do.
Narrowband though is not everyone's cup of tea for look. Some love it.
A really good narrowband with RGB stars installed to replace the narrowband ones (which inevitably are not attractive) is a popular image.
Narrowband requires longer subexposures (meaning more precise tracking and polar alignment, more accurate autoguiding etc etc) and longer overall exposure times. Longer processing time. So keep that in mind if you don't want to do that then it won't be for you.
