In the Dome – A Tour of the Subaru Telescope

Earlier this month, I had the chance to observe from the summit of Mauna Kea at the Subaru Telescope using Hyper Suprime-Cam (HSC), the same camera we use in the new HSC survey search. I and my fellow observers got a great tour of the telescoped dome and also around the summit of Mauna Kea from our telescope operator Josh (thanks Josh!). Here’s the photos I took during the tour:

Dome Opening

I found this online today, and thought I’d share. The engineers for Hyper Suprime-Cam on the Subaru Telescope put together a video of the Subaru dome opening during twilight, You can find the original video here on a blog about the commissioning of Hyper Suprime-Cam, Subaru’s newest wide-field camera (Note:  the blog is in written in Japanese).

When you’re observing you don’t often get this view as sunset is one of the busiest times when you’re an astronomer getting ready for the start of your night (likely of one or a handful that semester) on the telescope. The data you currently review on Comet Hunters is the public archival data from Subaru’s Suprime-Cam. Each of those nights when the weather was good, something like below happened as the observatory prepared to start the nightly calibrations.
