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.
