Visiting the WIYN 3.5 meter

There are roughly 25 observatories atop Kitt Peak mountain, so there’s lots to see and do. I am visiting the mountain in order to use the Steward Observatory’s 2.3 meter Bok telescope (‘the 90inch’). One of the observers on our team was also scheduled to use a different telescope for part of the week; she is working with the WIYN 3.5 meter telescope, which is the 2nd largest optical reflecting telescope on the mountain (1st is the 4m Mayall). As a result, we got to take a quick peak in side:

From the outside, the WIYN 3.5 looks different than most telescopes. Its dome is of a more segmented shape than most spherical domes.

The scope set and ready to go for obseving.

The operator turned the scope on its side so we could get a look at the primary mirror. At 3.5 m, it's pretty big.

It's a big scope.
