    Same dish as Owen's Valleys', including the ao setup, just has a nice helmet :D. other than that just normal calib's such as pointing and flux. The dish is like a sail in the wind so pointing can be tricky, sometimes nodding off 10 arcsec in a 2h period. For the 230 ghz receiver we do use a chopper for the secondary, chop every sec or so

    Nice video! I just wonder...for the astronomers who get into the field because they like the equipment and being on the summit, I wonder how things are changing. Long ago people looked into an eyepiece with their eyes and made exposures on photographic film at the telescope in the cold dome. Then came ccd cameras, and observers still used them on-site but from a warm control room. But with the development of robotic remote-control and space-based telescopes, I wonder how long it will be before all astronomical research observing is done over the internet from your home institution - or maybe it already is? Do astronomers still work at telescopes, or is it only the technical staff that is up there nowadays?

      Hi Poly. This is Alain Khayat, the scientist operating the telescope here. This was ten years ago now and we were the very last people to do science with the Caltech Submillimeter Observatory before it got decommissioned. It needed a lot of work to operate this beast and be able to do science with it. Remote observing is currently the thing to go for nowadays, but there is still the need to have technicians on the telescope to cool down the dome, fill in liquid Hydrogen/Helium, etc, and make sure the observing night goes according to plan!

    The segmented primary mirror doesn't do real-time correction right? Pretty they are active optical systems rather than adaptive!

    Hmm I always wonder how I can help to support this video series... Obviously providing an interesting place to visit for the show would probably help out the most but not everyone is in academics so I'm left to think about donations or some other way of helping out negate the cost.

    I have now discovered this through the videos of a TH-cam star that does a complete documentation of this. A great video put to music is called Hawaiian heavens part 3 song is called alone tonight. I truly know nothing ,and amazed at this whole new area of life.my question to the scientist still there all these years later , not what you have seen, that's a secret,but why at sunset sun takes square star shape, switch. From round? Happy days

      @@Physics072 The statement was true, AND I will keep dreaming
      FI, I can put the tiniest light on my boat and it can be seen a mile away at night. But a flag the size of the one on the moon cannot be seen in broad daylight from a mile away.
      Try to pay attention, and try to dream. Those are the hallmarks of genius
      (Btw, I do doubt a candle flame could be seen from earth with even something as powerful as the Keck scope, (dont really know!), but that fact is not even relevant to what I said in my original comment).
