M3 color CCD picture, made from CCD images taken at the Burrell Schmidt telescope of the Warner and Swasey Observatory of the Case Western Reserve University, located on Kitt Peak in southwestern Arizona. The contributing images were taken in June 1996 during the Research Experiences for Undergraduates (REU) program.

Image of the globular cluster M3, obtained with the mini-mosaic camera on a Nasmyth focus of the 3.5-meter WIYN telescope on Kitt Peak. The camera uses two 2k x 4k SITE CCDs, mounted side by side to create a 4k x 4k field of view. The gap through the middle of the image shows the separation of the chips. This is a 120 second exposure in the B passband.

This image of M3 is a combination of a B-band image and a Z-band image (Z is approximately from 8500 to 9500 A) taken on March 22, 2003, at the WIYN 3.5-meter telescope in 0.4 arcsec seeing. The image was taken with the WIYN Tip-Tilt Module (WTTM). It is used to study the many variable stars in this globular cluster.
