Well done! Magical.

Paulo, I don't understand the following statement in your blog: "If there is some “land” in the frame, ground features will be blurry as result of the Earth’s movement." You are using a tripod, shouldn't you, the tripod and camera, along with Earth, be moving together?

Thanks David. What I mean is that you can stack the images for star trails, or for accumulation. In the first case the ground is frozen, and the movement of the stars is recorded as a trail. In the second case, the stars are aligned (say using 10 shots of 20 seconds each), but the ground is not aligned. If I were a PS wizard, I could probably make a composite using the ground from one shot, and using the aligned sky part from the 10 shots.

Ah, OK that makes sense. I think one way to do that is to make a mask to remove the land from all but one of the images placed at the top of the layer stack. The quality of the Milky Way image is terrific.

Well done! the sky seems very clear.
There is a chance i will be visiting some places alongside the coast of Alentego in around beginning of september...
My girlfriend Paula is from Portugal (near Coimbra) and like you, very much likes the coast.
Will have a another look of your coastal photographs before i go...
btw i read you are educated as a geologist- my study was physical geography; also have my own view on landscapes...

Thanks. September is a good month to visit, the area will have fewer tourists by then. I will probably be in Longueira, feel free to drop by.

Very nice images. Looks like it is nice and dark there. The little hilltop in the second one compliments the galactic core very nicely!

I encounter the blurry foreground issue if I use the Astro Tracer feature in my K-1. That feature moves the sensor to follow the stars which allows for longer exposures before seeing trails. It works fairly well up to 4 minutes or so but that movement blurs the foreground. So what I do is exactly what you mentioned, get a fixed shot with the foreground sharp and blend that over the blurry foreground of a tracer shot.
