MagAO-X 2019B Day 3: The Telescope Proper

Today marked MagAO-X’s last day in the clean room at the halfway house and its first night in the Magellan Clay dome.

The day started with a lift (now almost mundane) of the optics table off its legs and onto the transport cart. We pushed it out the clean room doors and onto the back of the waiting Isuzu flatbed for its journey of a few hundred feet up to the Clay.

A few minutes later, the instrument was unloaded at the Clay and staged for its eventual afternoon trip up the elevator to the Nasmyth. In the meantime, the legs were put in position and the electronics found itself on the way up the hill shortly thereafter.

The goats were suspiciously absent today, but Gary materialized in the afternoon to satiate our wildlife-sightseeing needs. After a short break, the instrument table was elevated up into the Clay, craned into the air, and rejoined to its legs.

MagAO-X (minus the electronics rack) settled in on the Nasmyth.

Olivier arrived at LCO just in time for dinner (as well as a cup of coffee [or several?]). After a tour of the facility, a quick spin on the Nasmyth, and a demonstration of cart racing by Laird, the team stopped to watch the sunset, as is tradition.

With one day more to first light, the song of the day must of course be “One Day More” from Les Misérables:

MagAO-X 2019B Day 2: Chillin’ in Chile

Hello XWCL! This is my inaugural blog post so buckle up because it is going to be a sleep-deprived ride. Laird and Alex spent the day prepping the instrument for transport to the telescopes while Jared, Joseph, Kyle, and I were putting the “finishing touches” on various pieces of code. Kyle, Joseph and I were able to get the auto_focus code running fairly smoothly. The question of the day seems to be on the focus curve plots, to show or not to show?

Joseph Daniel Long and Kyle, working hard or barely working?

Some burros decided to hold us up from going to lunch, but luckily they were very cute. There were a couple exciting animal sightings today!

Pre-installation Safety Meeting

Jared led the pre-install safety meeting to go over logistics of packing up the instrument, driving it up to the telescope, and installation.

Juan acted as our translator for the meeting

After dinner we began the decabling and packing up process. It was hard disconnecting such cooperative DMs but it had to be done.

And That’s a Wrap!

Once the cables and eyepiece were removed, and the instrument was closed up, we shrink wrapped the entire instrument.

MagAO-X is packed up and ready to go! Since MagAO-X is going to be installed on the telescope tomorrow I think it is safe to say that we will be running with the

MagAO-X 2019B Day 1: Black Friday Specials

Just for today, my friends, we have an unbeatable special offer: with each concurrency bug you find, we will throw in another concurrency bug for free!

And, if you call now, we will throw in a semaphore collision bug at no charge! That’s a $49.99 value!

Call now! Or, if you prefer an event-driven programming model: let us call you with this exclusive offer!

Okay, now that I’ve gotten that out of my system: we have been vexed by concurrency bugs today. These are the absolute worst. To reproduce them, you must get everything just right. (In astronomical instrumentation, that can sometimes literally mean the stars aligning.) Then, once you’ve reproduced it, you’re still only halfway to figuring out which element of your system caused it.

To make a long story short, my PurePyINDI library wasn’t equipped for the huge numbers of elements Kyle wanted to control. Once I sorted out the locking in PurePyINDI, Kyle was able to apply his eye doctor script (previously blogged about) on more than the previous maximum of 36 modes. (Modes, for the uninitiated, are a bit like “things that can go wrong”. The more modes you can take to the doctor, the better your images will be.) Now we can theoretically access the 1000+ modes CACAO spits out when we take a system response matrix, and make our images very sharp indeed. On the way there, we get a bit of an Eye of Sauron look:

The goal is to put all the starlight in the center.

I’m not even going to tell you about the bugs in the linear stage logic we shook out today. As soon as we squashed one, we found another, more subtle one. And another. Until we were all quite sick of stages.

This was also the day of a very important MagAO-X ceremony. Today, at 9:00 A.M., Laird and Alex unveiled the dedicatory tailpiece and plaque, which surround (and cover, when not in use) the hole for the MagAO-X eyepiece.

Here’s a closer look:

For some reason, I’m the only one with a middle name shown.

According to Professor Close, it is traditional for a new instrument to be adorned with a tailpiece as a sort of maker’s mark once it’s complete. Great work, everyone!

MagAO-X 2019B Day 0: Thanksgiving Arrival

Maggie, Joseph, Alex, Kyle, Laird, and Jared arrived at LCO today to prepare MagAO-X for our first time on-sky.  We missed thanksgiving with our non-LCO families, but the chefs made us turkey so we got a good holiday meal (thanks guys!).

We’ve already started MagAO-X back up and are making a bunch of last minute tweaks to get it ready.

Our cleanroom friend couldn’t quite believe were are back so soon!


MagAO-X 2019B Blog Rules:

  1. There will be at least one blog post each day
  2. The blog post of the day will have a song of the day

The song of the day is The Thanksgiving Song by Adam Sandler

MagAO-X 2019B Unpacking Day 12: Traditions

It’s an old MagAO tradition to take selfies for our moms in the mirror that gets you around the bend at the summit.  Long story, but it’s also tradition for it to be poop covered unless Alan is here.

Hi Mom!

Tonight’s song is “I miss the misery” by Halestorm. Since the casual reader of this blog hasn’t signed up for Lizzy Hale with the power on, here’s a “subdued” version of it:
