M3 Globular Cluster color imageM3 Globular Cluster - Kodak DX7440 Easyshare digital camera. 34sec exposure on the 20" OGS at the HRPO. Easy to see the difference between a cheap Easyshare digital camera and a NOT cheap CCD! Still cool, though. The hardest part was getting it centered and focused. All done blind because M3 wasn’t bright enough to show up on the camera’s LCD display! 33.2KB.
