"You keep demonstrating you are not an optics guy and unfamiliarity with digital imaging especially. "How large are the pixels" is like somebody asking "Where is the tightening area on a nut?". A pixel is just a pixel, it is a fundamental with no dimension. I know you are going through malihini meltdown so you are of little notice to me."
What a load of codswallop.
Astronomical instruments use detectors with pixels matched to the resolution of both the instrument and telescope. They have a physical size, usually, for infrared observations, measured in microns. If they didn't, then 1) array manufacturers are designing mini-black holes and 2) how can I, or anyone else, see individual pixels on an array if they are dimensionless?
I really don't know what's wrong with you, but something isn't right.
"A true knowledgeable scientist comments on the Pluto digitial imaging:

“We went from having images that were maybe three pixels across to images thousands of pixels across, so we are essentially seeing Pluto for the first time in terms of its landscapes and geological story. It’s completely new and completely spectacular,” said John Spencer, a member of the science team at the Southwest Research Institute in Boulder, Colorado."
Of course the images of Pluto cover so many more pixels on New Horizons. The images were taken a few thousand miles away rather than several hundred million miles from ground-based observatories.
Your understanding of how things work in physics, astronomy and optics is so profoundly wrong it's mind-boggling.
Dimensionless pixels. Jeeze...
