Can we move on from EP inverted views !  This is EAA and north is at the TOP and directly comparable to starcharts - please :-)

Sorry if I confused anyone but by inverted view I was referring to black against a white background. I am just so far removed from EPs that I think everyone is on the same page like me but apparently no so

Also note the above calculation does not consider the OTA (or camera lens) required image circle size to deliver light to the entire image sensor area.

Or about a million (kidding) 1/3" type sensors ... and we get an idea about the economies involved and why there are a ton of cameras using them.

For each 1 degree FoV need to be covered in the sensor diagonal direction (not horizontal nor vertical direction), multiply

E.g., need OTA focal length = 344mm for a type-1/3" sensor to cover a 1 degree FoV object in the diagonal direction.   Fl=172mm to cover 2 degrees.

To invert or revert, that is the question, however is this not a function of the optical train, excluding the camera (eye).
