A new instrument at the Subaru telescope has achieved first light - it can monitor 2400 separate objects simultaneously - by AndyTomaswick
Unfortunately, these sensitive instruments won’t usually be used to capture rainbows, but theoretically, the Wide Field Corrector could. It is a seven-lens optical system developed specifically for this upgrade that allows Subaru’s operators to correct for errors in image collection before they become a problem.
There are also some supporting systems to enable the actual data collection to take place. n addition to the SpS, the PFS utilizes a giant 8960 x 5778 pixel CMOS camera known as the Metrology Camera System to track where precisely the fibers collecting the data are located. If any are out of place, it could throw off the data the system collects.
All of these upgrades come with high hopes – the goal of the PFS upgrade is literally to understand where the universe came from and where it’s going. It will coordinate with the Hyper Suprime-Cam already installed in an effort to “reveal the nature of dark matter and dark energy, structure formation in the universe, and the physical processes of galaxy formation and evolution.That’s a lot for one telescope upgrade, but it will surely have lots of data to analyze.
