MAGIC Prime Focus

The MAGIC Telescope
August 28, 2015

The MAGIC telescope has the biggest telescope mirrors in the world. I’ve always wanted to get up the green tower to prime focus, where the light is focused onto the camera. I finally got up there in July 2014. Even better, my friend Carolin Liefke (from the Max Plank Institute) had a camera with a fisheye lens and the skill to make good use of it. You can read more…


New Cherenkov Telescopes

April 27, 2015

  The Cherenkov Telescope Array (CTA) is negotiating with the IAC to site more Cherenkov telescopes on La Palma. It’s not guarenteed that they’ll come here, but it’s highly likely. What is certain is that they’re going to build a prototype here. So what’s a Cherenkov telescope? The oversimplification is that it’s a telescope to look at gamma rays instead of visible light. For more detail, see this article on…


Visiting the Observatory at the Roque de los Muchachos, 2010

La Palma is home to one of the three most important astronomical observatories in the world. (The other two are Hawaii and the Atacama desert in Chile.) The observatory sits at the top of the island, at the Roque de los Muchachos. It’s a fascinating place to visit, but it’s not normally open to tourists – they’re too busy doing science. However, the IAC who run the site are organising…

R.I.P. Florian Goebel

Florien was the project manager for MAGIC II, the second of the huge Cherenkov telescopes at the Roque de los Muchachos. The telescope was due to be inaugurated next week, on the 19th. That’s been delayed now, because somehow he fell from the prime focus tower in the dark last night. The tower is about ten metres (33ft) high, and Florien’s dead. I only ever had one conversation with him….

More Magic

Fitting another mirror segment to MAGIC II The MAGIC gamma ray telescope is getting a twin. MAGIC II will work together with MAGIC 1 as a two-telescope array. The first thing you notice about MAGIC is that it’s huge. The mirror is 17 m (55ft) across. This is because Gamma rays never reach the earth (unless they come from an atomic bomb). What the telescope is looking for is something…
