Touch down on Little Man

I watched a Coastguard helicopter doing some circuits, hovering and then touching down on Little Man. If you look carefully you can see it as a white dot above the peak. Whether it was training or rescue I couldn't tell. The distance is close to 4K.

I usually use my iPhone camera when I'm away from home but here I've used my Sony RX 100. On the phone screen it's hard to tell what quality the images are. What does this look like on a computer screen I wonder ?
