> Where Harbison had previously captured an image of the Nebula on a 10-11 pixel scale, using the QHY 16200 camera would change that to a 1.6-pixel scale of the constellation Orion.

Pixel scale here seems to mean how many arc-seconds a pixel covers. The full moon (or one's thumb at arm's length iirc) substend about 30 arc-minutes (half a degree)
