I have a basic question... I was wondering how the camera/software/firmware deals with binning. If I bin my STT-8300 at 2 x 2 is the data for the 4 pixels summed or is it averaged? I have recently seem several posts in various forums stating that binning 2 x 2 gives you 4 times the signal. However, I have always assumed that the 4 pixels are averaged and the S/N gain from binning is based on the averaging of the pixels. Dean J.
