El Hierro


Originally, the final exam for the Starlight course was going to be the 26th of May, and that was when the project had to be handed in. So I booked flights to visit my friend in El Hierro for the long weekend afterwards, on the basis that I'd have earned a break by then.

Then the course teachers found that it suited them better to move the exam to the 2nd of June, and decided we could hand the project in then, too. Of course nobody objected.

Well, the flight was booked anyway, and I knew that my friend would understand if I spent some of the time putting finishing touches to my project, and/or studying for the exam.

And then my friend found that she had to move house while I was there.

So the relaxing long weekend largely consisted of lugging things out of one house into another, and cleaning the old house. Quite a lot of the rest was spent working on my project. My digestion started acting up again.

And you know what? I still had fun.

Mostly it was being with my friend. In spite of high stress levels on both sides, we had some good laughs. And I love El Hierro. She's moved to a particularly lovely part, near the Parador.

I woke very early one morning and went for a walk and saw the crescent moon rising near Venus and (I think) Mars.

We went down to the Parador for delicious (if pricey) sandwiches and to use the Wi-Fi, where we met an albino pigeon who obligingly posed on the roof for quite a while.

And once we were in the new house, we also heard weird noises in the night, which sounded something between a furious tom cat and a duck, like this . I wasn't exactly scared, but I was rather glad that I was inside the house and the whatever-it-was outside. I think I'd have felt decidedly uncomfortable about it if I'd been camping.

I can see why people have mistaken them for witches or even the devil, but actually it's a nocturnal seagull called Cory's Shearwater, or in Spanish a Pardela Cenicienta.


And with all that, I still made considerable progress on my project.

Bunking off



Yesterday afternoon I should have bashed on with the Starlight Guide project and housework. Instead I took a couple of hours off and met my friend in Los Tilos. The bar there is popular with small birds (a kind of chaffinch, I think) and I couldn't resist trying to get a photo.

There was a catch, of course. Flexible though my new compact is, there's a short delay between pressing the button and the shutter firing. It's less than the previous compact - maybe half a second instead of a full second -- but it's good for lots of shots of a bird that just flew away.

Luckily persistence and patience eventually paid off, and I got a shot I'm fairly happy with. But I still plan to go back with the DSLR and try again, in better light.


And then we had a nice little walk in the drizzle, down to the water channel. This time the compact came up trumps. The trick with flowing water is usually to set a slow shutter speed, which makes the water look wetter. This was shot at half a second, and I couldn't have done that with the old camera.

A Night on the Mountain

The last practical activity on the Starlight Guide course was a trip to the observatory at the Roque de los Muchachos. The bus left Santa Cruz at 2:30 pm, and when we arrived we left our stuff in the dormitories that I didn't even know they had up there (they converted one of the houses some time ago for groups like ours, four bunks to a room, bathroom shared between four rooms). We had the head of the observatory show us round the Newton and Herschel telescopes, and the Swedish solar tower (the best solar telescope in the world). After dinner we watched the sunset, then had a class on astrophotography with Daniel Lopez (very cool). That was followed by stargazing with two amateur telescopes, and a visit to the control rooms of Grantecan and the Herschel while they were working. Of course I took tons of photos plus videos of the talks. We collapsed into bed at 3 am. I was really pleased that I'd brought along a spare camera battery.

I didn't sleep too well. The room had an emergency light in the ceiling which was too bright for poor, delicate little me. So I got up early and went for a walk, where I took yet more photos.

After breakfast we had a class on infrarred and spectroscopy, followed by observations of the sun. (NEVER do this unless you know what you're doing. You can go blind instantly.) There was only one sunspot, but it was fun. Then we went around Grantecan, including the places they never normally show the public. Including places I've never managed to get into before, like the aluminizing room.

And I ran out of space on my camera card. It's a 16 Gb card, and I filled it.

So I deleted obvious duds and hunted through the menus and worked out how to drop the picture quality. And I took quite a few more before the second battery died of overwork.

I haven't managed to edit my way through 16 Gb of photos yet, which is why there's no photos in this post. I have ten days to revise for the exam and write a 4,000-word project in Spanish, and I won't have lot of time for very much else. It doesn't help that I already booked a long weekend with my friend in El Hierro, thinking that I'd have finished by then.

Really cool time lapse

Astronomy Picture of the Day is a great site. And yesterday they had a fantastic time lapse shot in the Teide national park in Tenerife.

But the coolest bit of all is that Daniel Lopez, who shot this video, will be giving a talk to us trainee Starlight Guides on Friday night.

Sickening, aren't I?
