Comparison of the field of view of VST/OmegaCAM and other telescopes

This image compares the field of view of OmegaCAM on the VST and several other telescope/camera combinations. The VST field is about four times the area of that of the Wide Field Imager and covers an area of sky more than 300 times greater than the imager on Hubble with the widest field, the Wide Field Channel of the Advanced Camera for Surveys. The image in the background was taken from the Digitized Sky Survey 2 in the outer parts and the new VST image of Omega Centauri in the centre.
