Stereo Photographs from the VERITAS project
Photographer : Brian Humensky
The pictures here were taken by Brian Humensky of the VERITAS
project while visiting the Fred Lawrence Whipple
Observatory at Mt
Hopkins and the Kitt Peak
National Observatory in early June 2004. Dinoj Surendran aligned
them with Pokescope.
The photographs are of several telescopes, including
Download: veritas2004june.zip (67 Mb) contains all the photographs thumbnailed on this page, and this GWD file that you can view on a GeoWall with
Wallview. The picture order in it is similar to the one on this page.
veritasstereo_anaglyphs.zip
(33 Mb) has anaglyph versions of the same photographs. They are on this webpage too; whenever you see a picture called blah.jpg, type in the url window blah_anaglpyh.jpg (Note the misspeling!)
Mark SubbaRao put some of Brian's pictures together to form a panorama - but there was unfortunately one missing picture: rectangular, dome format.
Technical note: Several photographs look like duplicates, but aren't. There are
slight differences in the pictures themselves or in their alignment or
cropping. Pictures were taken using a bar with three positions, in
left-center-right order. Therefore, if you see two pictures, say
1june_829_830.jpg and 1june_829_831.jpg, the former is a left-center
pair while the latter is a left-right pair and looks 'more 3d'. For
some people 'more 3d' is 'too 3d' so both pictures were left
in. Similarly, if you see a picture labelled 'mid'
e.g. 1june_829_830mid.jpg then the alignment was done with some object
at a middle distance from the observer and the non-mid picture was
aligned with some object closer to the observer.

Welcome to the Fred Lawrence Whipple Observatory at Mt Hopkins!

The sign says "... road ahead is single-lane, unpaved and steep", proving beyod a doubt that we are in Arizona :) |

The first VERITAS Telescope
This telescope is being converted in summer 2004 from a prototype,
and will eventually have to be moved (pity the
movers!) to the eventual site on Kitt Peak 90
minutes drive away.
|
A face-on view of the telescope. The diagonal squarish
yellowish-brown box sticking out at you contains a camera (assembled
at UChicago from parts made at Iowa State, Purdue and other
universities). The shutter of the camera is reflected in the mirrors
of the telescope (also reflected is the hill of scree on which the
photographer stood.)
|
|
The triangular bit is some other instrument that
we will document later. The blue stripes running SW-NE are actually
grey strips of duct tape holding the shutter together.
(Try to ignore the barrel to the right of the left picture...)
|
|
The structure to its left is a trailer housing the electronics to
acquire data from the telescope. The duct work coming out of the
trailer contains cables (mostly coaxial cables, a couple of optical
fibers, high voltage lines, power lines), which go underground and
into the telescope structure.

|
Same scene, later in the day. Note that only about a quarter of the dish is covered with mirrors at the moment, the rest will be put in over the summer of 2004.
|
|
|
Side view. The diameter of the telescope dish is
12m. The distance from the dish to the camera is
also 12m. |
|
|
As previous picture, but made lighter by changing the light intensity curve.

|
These folks are disassembling the camera on the telescope. They're standing on a SnorkelLift.

|
Brian writes, "the
mirrors have been covered with cardboard and plastic bags: a long story
involving alignment tests and the power outage. But at least they don't
reflect."
|
|
|
Here's one of the previous generation of telescopes, the Whipple 10m gamma ray telescope. The original structure was built in 1968, the camera and mirrors are much newer. It's also at Mt Hopkins Observatory.
|
|
|
The dish of this telescope is 10m in diameter and the camera is 7m from the center of the dish. On the camera is a cover that is taken off before an observing session.
There are cables running along the struts.

The red 2003 Dodge Neon (used by the photographer and actually very dusty - somehow the dust doesnt show in the photographs)
in the background clearly shows the scale of the telescope. The support structure of this telescope is not very high, so a pit in the ground was needed when the telescope was built.
|
|
|
Several face on views of the telescope. Near the
bottom right of the picture is the photographer, who
was standing on a balcony of the support building
near the telescope. Also visible in the reflection
on the mirrors is the air conditioning unit on the
building.

|
|
Back to the telescope and the Neon.
|
|
|
Behind the 10m telescope (what we were looking at just now) is a support building.
|
|
|
Behind the support building is another telescope, in a dome. This is either the 48" or the 60", Brian's not sure.

Photographs from Kitt Peak
The VERITAS telescope will eventually be moved to Kitt Peak. Here are several shots from it... you can work out what you are looking at from this documentation at the Kitt Peak National Observatory website.
|
This is where the VERITAS telescopes will eventually be located.

This pleasant looking lake is home to every evil little bug and pest
known to humanity. That's admittedly hyperbole, but you get the
idea. Swimming is not recommended. |

McMath-Pierce Solar Telescope
This interesting structure is the McMath-Pierce Solar
Telescope at Kitt Peak.
