    MagAO Commissioning Day 30: Local minimumWell, we are almost home… we made it to the Dallas airport. When we left in early November, the election had just concluded and I was still eating Halloween candy. Thanksgiving has come and gone. And now that we are back in the US, we are hit with the usual full-blown American Christmas with music, ...

    MagAO Commissioning Day 29: The After PartyWe’re off the mountain! Laird, Katie, Jared and TJ finished putting MagAO to bed yesterday, and made the journey down to La Serena. We spent one night there, and with Laird’s folks took some time off to celebrate. We have a long overnight flight to Dallas ahead of us, but we’re almost home. Some quotes ...

    LCO StyleHola, it’s Vizzy!  I work hard to keep my fur fuzzed, so I was asked to do a special guest post on LCO style.  MagAO has been immersed in the culture of LCO for a month, and they are a stylish bunch indeed.  Here we go! LCO is a pretty stylin’ place. What with the jumpsuits, clean room ...

    MagAO Commissioning Day 27: Time for BedThis is my least favorite part: packing everthing up, getting organized, finding all of our lost allen wrenches, and taking a zip-tie inventory. The ASM came off the telescope yesterday, and rode down the hill first thing this morning. The last major operation was to unbolt and crane the NAS off the telescope. Once the NAS came off, ...

    MagAO Commissioning Day 26: Taking Clio and the ASM off the telescopeWhen you bring an expensive, delicate instrument to an observatory, you want there to be people like Juan Gallardo who put their full attention and serious effort into the procedures and operations for mounting and dismounting your instrument. Yesterday evening, we all met in the library/conference room, and Juan briefed us on the procedure ...

    Jared Males

    After the dome closed at sunrise we shutdown VisAO, Clio2, and the ASM.  Here are the big moments. (Don’t get the wrong idea. We all actually love Clio – it just became the scapegoat for any and all problems that occurred in the last month.) It is indeed time to go home.

    MagAO Commissioning Day 25: So Long to the NightTonight is the last on-sky night for MagAO in 2012. Don’t panic. We’ll be back with a vengeance in Spring, 2013! We began the night tonight by looking at a bright star that Runa chose for calibration. Upon further inspection, and much to our surprise, it turned out to be a heretofore unknown binary! We’re calling it “Runa’s ...

    MagAO Commissioning Day 24: Rookie postThis is my first post…had to do it some time…. Tonight was divided up into two separate halves. In the first half of the night, we went back to some faint guide stars to both confirm that the AO could reliably lock on them, and to test out a few bugs on Clio. The previous night, Clio ...

    MagAO Commissioning Day 23: Galaxies are ...faintWell, we tried out our faint guide star modes tonight. We locked on a 14th magnitude guide star in bin 3, and a 16th magnitude guide star in bins 4 and 5! We were getting down to 90 milli-arc-second PSFs in K-band, where diffraction-limited is 70 mas, while correcting fewer than 100 modes. In ...

    Atmospheric Phenomena of LCOHere at LCO, we spend a lot of time staring at the sky, and not just with our instruments! I’ve noticed, for example, that the Belt of Venus is quite prominent and beautiful at sunrise and sunset. For those of you who’ve never noticed it, the Belt of Venus is the pink band of light ...

    MagAO Commissioning Day 21: High Res VersionThings are always exciting here on the MagAO project. But nothing – not earthquakes, viscacha attacks, not even non-orthogonal basis sets – can keep us from doing what we came here to do. Now that we are on-sky, we are taking advantage of the *amazing* 0.5 arcsecond seeing common at LCO to take some nice ...

    MagAO Commissioning Day 20: Vizzy QuakeTonight started with a hard to understand communications problem between our AO system and the telescope control system (TCS). It’s been working for days, but tonight we started having some messages get dropped. We have to keep the elevation of the telescope above a certain value to keep our delicate mirror safe, and this communications ...

    For all of the non-astronomers out there (hi dad!) who have been patiently wading through our blog because they love us, here is a very brief crash course on AO. We thought that this might help you to understand why what we’re doing here at MagAO is so exciting. The first important concept is that, in ...

    MagAO Commissioning Day 18: Focused on skyToday we were down 50% of our tenured professors and 50% of our Italians.  Phil left yesterday and Simone and Enrico left this morning.  Therefore, I was a little worried because their presence is definitely missed.  Luckily, it was a good night anyway! We weren’t socked in with high cirrus like we were yesterday, so we ...

    Jared Males

    MagAO Commissioning Day 17: Back on Sky With A FeverThe unofficial battle cry of the MagAO project over the last few days has been “More Cowbell!” as we try to get a high-order basis set that keeps our actuators happy. To get the truly amazing image quality that our system is capable of, we need to find a set of shapes for our mirror that ...

    MagAO Commissioning Day 16: Clio and VisAOToday we worked more on interaction matrices and calibrations during the day. In the evening, Phil and T.J. spent some time optimizing and testing Clio.  Clio got to move to the big computer in the Clay control room for the first time (instead of running it off Phil’s laptop).  Here are some pictures of the big ...

    MagAO Commissioning Day 11: A calibration riddleHere’s a riddle for all you AO fans out there: What aberration can be sensed but not corrected? Usually an AO system has the opposite problem: There are aberrations you can correct but not measure.  And of course, there are all sorts of aberrations you can neither measure nor correct, like the very highest spatial frequencies. ...
  • Vibrating Crow

    Jared Males

    Vibrating CrowOur CRO is a very fast f/1 optic, and our ASM makes an f/16 beam. So motions of the CRO are amplified by a factor of 16 in our focal planes. We can see this on the VisAO CCD47 as a dancing image due to small mechanical vibrations of the telescope. The MagAO project is adding ...

    MagAO Commissioning Day 10:  Thanksgiving, Lollipops, and Bird PoopHappy Thanksgiving!  I am thankful for clear skies, low winds, and contactless continuous facesheets. We are employing fine Italian craftsmanship to obtain the interaction matrices for our AO system, using the “penina” internal light source (an artifical star) and the CRO retro-reflector.  These are crucial calibrations for the feedback loop to create the desired shapes on ...
