What does ODI stand for?
One Degree Imager
What year was it first envisioned?
2000
How tall is it?
Approximately as tall as Shaquille O'Neal.
How big is the field of view?
1 degree square, which is an area 4 times the size of the full moon.
Who is paying for it?
The WIYN partners (Wisconsin, Indiana, Yale and NOAO) and the National Science Foundation (NSF)
What does the tip/tilt do?
Increases the image quality by stabilizing the images. The tip/tilt or OTA will be able to compensate for images motion due to atmospheric turbulence, telescope shake, and tracking errors by locally shifting the image directly within the CCD.
Who designed ODI?
Gary Muller did the instrument design and Charles Harmer did the optics design.
