What is the CHARA Array?
The CHARA Array is an optical / near-infrared interferometer located on Mount Wilson, CA. The facility is composed of six 1-meter telescopes, a beam synthesis facility, and a beam combination laboratory.
What is the longest baseline between a pair of Chara telescopes?
330 meters
In terms of the number and size of its individual telescopes, its ability to operate at visible and near infrared wavelengths, and its longest baselines of 330 meters, the CHARA Array is arguably the most powerful instrument of its kind in the world.
Where is Mount Wilson?
Mount Wilson, peak (5,710 feet [1,740 metres]) in the San Gabriel Mountains of the Angeles National Forest, southern California, U.S. It lies just northeast of Pasadena.
What is prime focus telescope?
Prime Focus is where a telescope or camera lens forms an image directly on the sensor of the camera. Field Flatteners correct curved focal planes. Focal Reducers reduce the focal length of the telescope, make the focal ratio faster, and the field of view wider.
Is the Hale telescope still used?
It was completed in 1949 and is still in active use. The Hale Telescope represented the technological limit in building large optical telescopes for over 30 years.
How many telescopes does Mt Wilson have?
There are three solar telescopes at Mount Wilson Observatory. Today, just one of these telescopes, the 60 foot Solar Tower, is still used for solar research.
Who owns Mount Wilson?
the Carnegie Institution of Washington
They are now separate entities, and, although Mount Wilson is still owned by the Carnegie Institution of Washington, it is operated by a consortium known as the Mount Wilson Institute (MWI). MWI has updated the instrumentation, including the 60- and 100-inch reflectors and the solar telescopes.
What magnification is prime focus?
If you divide the telescope focal length in millimeters by 50mm the result is the magnification. As an example, my 4” refractor has a 600mm focal length. Therefore the magnification at prime focus with a camera is 600mm divided by 50mm or 12 times magnification.

How many telescopes at Mount Wilson?
Do you need an eyepiece for astrophotography?
If your goals are to capture deep-sky astrophotography images, you’ll want to use the prime-focus method that does not use an eyepiece or Barlow lens in front of the camera. Yes, this means that you will be using the fixed native focal length (magnification) of your telescope to photograph all objects.
Can I use 2 Barlow lenses together?
Good news, you can stack two 2x Barlow lenses and get the same 4x power! Stacking Barlows doesn’t add the factors, it multiples them – thus stacking a 2x with a 3x gets you 6x.
