On large telescopes trails of MegaConstellation’s satellites will appears
significantly defocused because of their relatively short distance. Because of
such effect their apparent surface brightness will be, under a range of
conditions, almost constant during their apparent sweeping on the focal plane
of such large facilities. A few simple relationships are worked out and
discussed to show the apparent brightness of such trails, in order to evaluate
their impact on operations of large optical ground based facilities.
