Ah, but you're redefined the scope of reach!  Just how long is the lens
you used for this project?  Or, just how small is your sensor? I can see
that you don't need high spatial frequency, scintillation pretty much
wipes out resolution at that distance.  Great job though!  I am
surprised and impressed at the detail you captured at that distance.
