Personal Outside the Bok by Jesse Rogerson|Published 16 February 2014|1 comment Haha. the Bok and the Bike. The Bok 90inch telescope towering over my tiny motorcycle. The hand railing you see about 2/3rds of the way up the structure is known as the ‘Bok Walk.’ The white donut to the bottom right is the original cement mirror blank for the Bok. Since most telescopes are actually built before their mirror is completed, ‘mirror blanks’ are created in the exact dimension/weight of the mirror-to-be. The blank is installed so that the telescope can be balanced in advance of the mirror arriving. After it is no longer needed, the blank can become an exhibit piece. The hatch leading from the telescope out onto the Bok Walk. It offers a fantastic view. This is taken from the Bok Walk looking over the road coming up the mountain. The Bok (left) and the Mayall (right) telescopes. The Mayall 4m is one of the more famous telescopes on the mountain. It is the highest elevated telescope at 2120m, which is actually taller than the summit of Kitt Peak itself (2098m). [Roll mouse over to animate]. Heading to dinner before the night’s observing run I took a look back at the Bok telescope, among others. These ‘scopes are on the north-most part of Kitt Peak. This is shot is taken looking in the North direction.[Roll mouse over to animate]. This is the view from the Bok Walk at sunset looking south over the whole of Kitt Peak (the Sun is setting off to the right). If you roll your mouse over the image you’ll see the location from which I took these images. The Steward Observatory Kitt Peak Observing Station, erected in 1962.
