Not sure which setting is correct.

Hi all 

Just installed PHD2 and having a go a setting up camera etc. to get used to the GUI.
During setup I hit the detect button and was presented with 7.50 pixel size.
Checking the camera's website it says 3.75 pixel size.

Thanks to @JemC I have an understanding of binning and paid enough attention in school to realise 3.75 is half of 7.50. 
What I am curious about is, is this setting in PHD2 correct? (picture 1 - picture 2 is from the manufacturers website)

Thanks for looking.
Pete.

Interesting... This might be a guess, but perhaps PHD is assuming that the camera is 640x480, like, I suspect, is the most common resolution used for guide cameras.. or just treating it like a 640X480 chip, therefore doubling the physical pixel size??? Actually binning it 2x2 by default....

Like I sad I'm just guessing.

I couldn't find the 640x480 resolution - that is indeed what I use on mine. 
The penny has just dropped that this is half the resolution listed at the website - feel rather foolish now! 
Makes sense. Thanks.
