Hello,
I was lucky to be in this place during new moon last Friday night, so it was as dark as it gets there. I tried a startrail shot towards the north (with light pollution from the village of Milfontes), and then a Milky Way shot to the south, including the light house.
This second shot was the trickiest; I have tried different exposure times. The challenge was to block the rotating light hitting the lens, which I did by periodically covering the lens every 5 seconds or so, with a cardboard. But then the exposure could not be very long, to avoid too much trail in the stars… Overall, this shot took 63 seconds, with an effective exposure of around 25 seconds; with 63 seconds, stars do move…
Anyway, it is always amazing and nice just to be there.
Regards.
