M51 photographed from Butterpot Park (near St. John's) on February 10, 2007 by Chris Stevenson, imaged through R.B.'s scope - 15 minutes before it clouded over! Tracking was
not perfect for two of the four exposures, and no calibration was performed
whatsoever - just a quick snap (which was also be mirror-reversed, since a
diagonal was used). Canon EOS 350D, 4 x 120s at ISO 1600, co-added in Registax4, cropped and
levels)
