All the SALTICAM bits were unpacked, weighed & then put together this morning. Here's the instrument box, weighing in at 41.45 kg.
& in the other corner - the cryostat, at 7.85 kg. The whole lot, including all the electronics boxes & cables, came to just over 77 kg.
Here's the eyeball - the very impressive set of lenses that make up the front barrel.
From the other side, you can see the rear barrel of lenses & between the 2 sits the filter & shutter mechanisms. The brass ring belongs to the auto-guider.
The pick-off for the auto-guider pokes in between the rear barrel & the cryostat.
Here's the cryostat.
Through the cryostat window you can see the 2 beautiful big pieces of silicon that make up the 4k x 4k array.
Instrument PI & cohorts bolting the cryostat in place.
That's all the hardware together, then the cables had to be sorted out.
Going into its port in the rotating structure.
A good snug fit...
Even the instrument cover goes on properly now - this all seems way too easy!
Once connected up, the various modes of the instrument could be tested. The frame transfer mask works!
Next up - slot mode... That looks fine too :)
Then it was time to start setting up the alignment gear. A bar that attaches to the top of the rotating structure carries a hole with a cross-hair strung across it.
A laser's mounted below the rotating structure & shines up through a small hole in a plug that locates uniquely within the rotating structure to mark the optical axis.
You know the laser's aligned when the cross-hair produces a diffraction pattern up on the roof.
Good stuff - that's enough for today!
