On Thursday I went up to the Roque, and I was surprised by progress on the Large Size Telescope. Every time I see it, it’s more impressive. Most of the mirror segments have been fitted now. I’m looking forward to the day they remove the white covering and replace the reddish brown counterweght with the camera support. I believe the inauguration is planned for October.

There’s still lots…

This is how the Large Size Telescope site looked yesterday. The big circular base for the telescope seems to be almost complete, as does the square base for the tower. The telescopes either side of the LST site and a little in front of it are the two MAGIC telescopes, which are similar to the way the finished LST will look. You can read more about the MAGIC and why…
