Subject: Re: Best planetary imaging camera
I really don't see how the Flea 3 camera has any real difference. Electronics wise the cameras are pretty much he same as the Flea 2. It's more about the CCD sensor in the camera than what camera hosts it.
And the key things for Sensors is the size of the pixels and the Type of CCD.
Very small pixels collect very little light but record more detail per pixel. Larger pixels record more light, but record less detail because they are bigger. Basically small pixels are like having extra magnification.
The other issue is CCD type, HAD versus Super HAD versus EXView HAD, which are listed in increasing sensitivity order. An EXView HAD camera is the most sensitive and therefore you can use less gains or run at higher frame rates for the same focal length.

planetary imaging - or is there yet another?
