This image was taken with the 8.2-meter Gemini North telescope. It was taken in the optical or visual part of the electromagnetic spectrum, without using the adaptice optics feature. Clicking on the image leads you to a comparison image with another one which is an IR image taken with the use of adaptive optics, which make star images sharper.
