Camera that can detect objects smaller than 0.3 arc seconds in space with sharper resolution

One Degree ImagerAstronomers from the Indiana University (IU) have found the new camera very much helpful in getting high quality images as reported in a press release.

This new camera is One Degree Imager camera, which offers a wide field of view, and it is located at Kitt Peak National Observatory in Arizona’s Sonoran desert and is present at Kitt Peak’s WIYN 3.5-meter telescope. This camera has the ability of giving good quality images across entire camera’s field of view. It can give images with sharper resolution even for objects smaller than 0.3 arc seconds while the field of view by the camera will be one degree across. One arc second is 1/3600 of a degree and there are 360 degrees in a circle. You can imagine that a normal human eye’s field of view is 180 degrees while forward facing in horizontal field.

This camera has a weight of 2800 pounds and is stabilized to motion that may be resulted from atmospheric turbulence, telescope shake and tracking errors by using a technology called Orthogonal Transfer Array charge-coupled device sensing.

“We can image entire star clusters, galaxies and groups of galaxies all at once, while still seeing the detailed features of each object. We can study a globular cluster made up of tens of thousands of stars, while at the same time imaging the individual stars that are packed into the cluster’s central regions. We can study a giant spiral galaxy while simultaneously resolving the individual knots of star formation embedded within its spiral arms. And we can image dozens of galaxies in a galaxy cluster, measuring the light coming from each individual galaxy as well as studying how the galaxies and their stars and gas interact with each other as they orbit a common center of gravity.” said Katherine Rhode, assistant professor, who studies distant globular star clusters.
