MagAO 2018A Day 17: The Wrong End of a Telescope

Proto3 has been detached from MagAO, and now MagAO is fully put away. Since this (northern hemisphere) fall will extremely busy with work on MagAO-X, it’ll be a whole year before we’re back here.

My check list for today:

  • Switch back to a day schedule all in one go
  • Take the last final exam for my first year of graduate school
  • Remove a 1000+ lb piece of scientific equipment from the top of a three-story tall machine

I’m happy to report that I accomplished all three, though it may be more accurate to say that I was a minor contributor to the last task. It takes a whole crew to remove the adaptive secondary mirror from the Magellan Clay telescope, and my main contribution was to help Laird keep all the various power, data, and coolant lines from getting away during the disconnect process. (Pink zip ties are the astronomer’s best friend.)

Since I was not operating a crane or lifting 80 lb load spreader bars by hand, I was able to document the process. Enjoy!

It's fun to stay at the Ell Cee Oh, yay!

I felt like one of the monkeys my sister studies, climbing up there.

To swap secondary mirrors, the telescope points parallel to the ground. There’s a crane that rotates as part of the dome which can very gently lift the ASM out and transfer it to a storage cart while the static secondary is in place.

Tomorrow, we leave LCO for La Serena (and Santiago and Dallas and Tucson, hopefully without issue). We’ll be back next year!


Last, but not least, here’s a song of the day about looking through the wrong end of a telescope.

And here’s a cover version I dug up by someone with cool hair:
