William Herschel discovered globular cluster NGC 6934 in Delphinus on September 24, 1785 and cataloged it as H I.103.
The image on the right was obtained in October 2002 by
Martin Germano with his
14.5" f/5 Newtonian stopped to f/6 (12"), exposed 110 minutes on hypered
Tech Pan 2415 film.
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.
