M3 Globular Cluster - Imaged by BRAS members Merrill Hess and Doug Inwood with the 20" Rithchey-Chretien and Apogee CCD at HRPO. 10x10sec exposure in RGB each. Calibrated and combined in Maxim DL by BRAS member Ben Toman. 86.3KB.
M3 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.
