Welcome to CFHT! Here's a small tour illustrating a typical day at the summit during an instrument change. Enjoy!
|
|
In the early morning, inside the dome... The 3.6m telescope is standing still, resting from the previous night. Ready for some action?
|
|
Personnel from the daycrew preparing the f/35 secondary mirror on the top-end ring to replace...
|
|
... the actual Prime Focus top-end. A giant claw is carefully brought around the ring...
|
|
... getting there...
|
|
Got ya! Time to go down...
|
|
Hello, please to meet you!
|
|
During that time, others are working at the other end of the telescope, taking off the instrument to be replaced (here, the Adaptive Optics Bonnette, or PUEO).
|
|
Tom in the cage and getting ready to grab the other top-end.
|
|
And up you go ...
|
|
A little bit more ...
|
|
Done ! And now we have a very different telescope
|
|
Some of the team take a break ...
|
|
... while some other work on the mezzanine, preparing an instrument, the Fourier Transform Spectrograph (FTS).
|
|
Working at the summit makes you hungry ...
|
|
Let's go for a ride to replace the electronic crates. It helps to digest the food!
|
|
Getting ready to move the AOB...
|
|
... back to...
|
|
... the mezzanine where it will rest until the next run.
|
|
Getting the Cassegrain environment ready for FTS...
|
|
Attaching the cables to the top of the FTS...
|
|
...and on the telescope floor you go! The instrument is mounted on a special support...
|
|
... and slowly put on the platform
|
|
FTS is now installed on the telescope!
|
|
The technical team discussing some aspects of the instrument installation.
|
|
Right voltage? Yeah!
|
|
Cables, cables, cables....
|
|
At the other end, some action is still taking place. Here, a baffling system is removed with the crane.
|
|
Paniolo Grant is getting ready for...
|
|
Going up? Mooommmmmy !
|
|
Wow! Nice view isn't it? Uh, can we just finish this cabling job and go down, pleeeaaease?
|
|
The telescope is now ready for some tests ...
|
|
... under the vigilance of the Roger and Yasu
|
|
Inside, in the control room, another team is starting the telescope balancing and instrument setup.
|
|
The computer room which is the brain of the telescope control system ...
|
|
Balancing the telescope - moving this way...
|
|
..or the other way...
|
|
Tom checking some electrical circuits. Ah, we should be able to open the dome tonight!
|
|
In the back room, the setup of the instrument is taking place.
|
|
Hmmm, we are getting signal. That's good.
|
|
Perfect! We're done!
|
|
Everybody has left and the control room is ready to welcome the observing assistant and the astronomers!
|
|
Well, maybe, if they can reach the dome through the fog... We did all that for this weather???
|
|
No comments!

|
And this is Hawai'i?
